There is this well cited argument that cloud companies like Google, Apple, Amazon, Facebook, and you-name-it are able to protect your personal data much better than you are able to. They have military grade security restrictions, better backup methods, and are able to do this much cheaper. Everybody is doing it so it seems to be OK to put your data into the cloud.
While this argument being absolutely true, people seem to forget that giving away your data to any third party is the root of many problems in the first place. It is not relevant to whom you are giving your data to. Yes, this also holds true for Apple's iCloud where many people think it's a save heaven.
Let me explain by examples.
Please note that the links provided are only a small selection of numerous facts on how the cloud is damaging your privacy in an enormous amount. This article mostly refers to personal data and not business-related data.
If a link is not available any more, please do use the Internet Archive WaybackMachine to find archived versions for a given date. Drop me a line if you do spot a source that should be not relied on.
The incidents collected on this page is only a tiny fraction of all incidents reported. Please use other sources like this for an overall picture. I'm just collecting distinctive incidents that support my point.
Disclaimer especially for tech-savvy people: Please note that I am using a simplified term of "cloud" which refers to storing data or metadata of us in the public cloud. I am specifically not referring to cloud-computing in terms of putting my own (encrypted) data in an S3 container or processing nodes that may be even stateless. With the exception of cloud processing services that turn bought devices into bricks after discontinuing their service. You see, it's complicated. If you know what a threat model is, you most probably know these things here already.
Losing Control
No matter, how secure your cloud vendor is storing your data, you are going to lose control. Same holds true for the European cloud.
With cloud-connected devices in your house, you might even lose basic services like heating or your lights. If this doesn't scare you already, how about losing control over your cloud-connected car? Even your cloud-connected sex toys record your "private sessions" to the cloud.
Not every data is lost or stolen on purpose. Mistakes happen. Whole MS Office suite apps might not be available all the time. Or cloud storage like Apple iCloud are offline from time to time.
Particular widespread hobby: people tend to buy smart home devices that turn into expensive waste after losing support from the vendor. Cloud-based car alarm system? Well, it's actually the perfect tool to locate and steal your high-class car.
You're losing exclusive access on the logs to your data. This is subtle but nonetheless important when it comes to sensible data.

Intermission: there was a severe Microsoft incident in 2023-07 which is probably the incident with the most impact worldwide of all times. Hackers had access to more or less all important systems of Microsoft for at least three years. Microsoft got extremly strong pushback from US government organizations. During the aftermath (2024-01), Microsoft got hacked by yet another hacker group, again accessing innermost systems. However, it did not get that much press coverage in the general media. The nature of this incident is a total security desaster for Microsoft which can not be trusted any more. This is because Microsoft can't replace all of their key infrastructure and their services (with potential backdoors) at once. This affected not only Azure, O365, all Windows hosts, GitHub, but all MS services and products.
I wrote a longer article on that Microsoft incident and included many external links, reports and sources to check the claims mentioned: Read That Before You Trust Anything by Microsoft Once Again

This article is discussing this notion from a different angle.
Data Gets Used Against You
You can't be sure how your cloud vendor is analyzing your data "for your best experience" or enforce arbitrary policies like the avoidance of nudity or strong language. And of course they sell the results of this analysis to third party companies. Same holds for user reviews. And of course your online purchases. Using a dating service should scare you when they give away your most sensitive data to advertisers.
Cloud companies consider you as their product, not their customer. They sell your data. Sometimes, they are not even interested in fixing security issues of your cloud.
Companies do give access to collected user data to their "business partners". Research shows that companies are exposing sensitive data with and without noticing more and more.

Inability To Delete
If you delete data in your cloud, nothing gets deleted for real. Truth is, the cloud vendor disables your access permission. Therefore, "deleted" data is used in the background and even re-appears from time to time.
- 2017-01: Deleted Dropbox folder re appeared after a couple of years. (dropboxforum.com)

Losing (Access to) Your Data
You can't be sure that you don't get locked out of your own data. This fortunate
People got locked out of their own cloud infrastructure. Sometimes you get locked out of your house. You even can get locked out from your cloud-connected shoes. Sometimes, your ISP is threatening to turn off your heating when you are using the Internet in a way they don't like. Politics can lock you out of your rented cloud-driven software products. Somebody is probably able to kill your pet over the Internet. Whole companies go offline when your cloud vendor wants.
You can't be sure that even cloud vendors are losing data.
- 2025-08: AWS
deleted my 10-year account and all data without warning: "AWS gave
me a present I’ll never forget: proof that no amount of redundancy
matters when the provider itself goes rogue."
- Lessons learned by the author:
- Never trust a single provider—no matter how many regions you replicate across
- “Best practices” mean nothing when the provider goes rogue
- Document everything—screenshots, emails, correspondence timestamps
- The support theater is real—they literally cannot help you
- Have an exit strategy executable in hours, not days
- "The cloud isn’t your friend. It’s a business. And when their business needs conflict with your data’s existence, guess which one wins?"
- "Every conversation revealed I wasn’t alone in being targeted by AWS—especially MENA. Hundreds of Reddit threads, websites, forums, all telling similar stories." "AWS didn’t just delete their data; they deleted their careers."

(Good) Cloud Providers Turning Bad
You can't be sure that the business model of your cloud vendor is changing so that they act differently compared to past statements. Sometimes your cloud vendor gets bought by a bigger fish. Or he is deciding to share your private data with others without your consent. Or he is introducing "quality of service" to storage performance which drags you down in production stage. Governments are beginning to sell sensitive data for profit as well.

Even your cloud-connected vacuum cleaner is selling information on your home to the highest bidder. Or it is providing a perfectly fine spying tool for the bad guys. Or it simply opens your door for the bad guys.
Furthermore, there is always the possibility of cloud vendor employees, who give away your data to interested parties as happened with Twitter 2022-12 (German heise). You have to trust every employee who has access to your data. All of them. Do you?

My favorite analogy here is the old sex education trope "wear a condom or you are exposed to all of the STDs of all of your partner's partners". Only in the cloud, the arrow of time is reversed. Everything you share you have to trust the company to steward, and not just the company as currently constituted, but all future versions, ownerships, partners and employees of the company.

You're the Product
Your privacy is of no concern for cloud companies. They don't care about the security of your data at all. Cloud vendors are even willingly hurting your privacy or health.
Many times, your data gets public because of a simple error. Also passwords. Even kids toys become spyware.
You don't have any idea on how manipulated cloud data is used to do psychological experiments with you.

Inability to Control What Goes into the Cloud

Losing Cloud Service
You don't have any influence on whether or not cloud services are discontinued by big companies like Microsoft. Game over. Lights go black. Your TV set as well.
Home automation is a potential risk in most cases. And if a service is not discontinued, it happens that years of data get lost somehow. Like twelve years of music files.
Cloud-connected devices destroy the internet and become expensive junk. Don't be surprised: any cloud-dependent device is going to stop working sooner or later. Even expensive ones.
Even temporary down-times of the cloud affect your life in many ways.

Forced Insecurity by Law and Agencies
The USA has laws forcing (cloud) providers to include back-doors that circumvent cryptographic protection. There are secret laws for secret agencies which force cloud vendors to secretly give away your information.
International cloud vendors ignore local legislation that is here to protect your personal data.

What To Do About It?
If you're still thinking of using public cloud services for your data, make sure to read about the conditions to do so you should be aware of.
There is no "undo" here. Once your data is out, your role in controlling this game is over. Outsourcing security has it's price whose currency is not Euros or Dollars but loss of privacy, control, and to its final degree: security.
Reclaim you digital life. Follow my postings on this blog and on Twitter - I am trying my best to stay independent and to own my own data.
You've got something to hide - even when you are not aware of it. And that's nothing that anybody is allowed to hold against you.
Arguing that you don't care about the right to privacy because you have nothing to hide is no different than saying you don't care about free speech because you have nothing to say. Edward Snowden
So in case someone tells you that he is pretty witty to let a cloud vendor host his data "because it's more secure", you can reply to this argument that the NSA has also a one of the biggest military grade cloud full of data scraped from your personal (cloud) data. Not against terrorism. Not at all: The leaked NSA selectors are not reflecting any focus on terror-related data. So much for this red herring.
"Hosting" your very private data there is nothing you're going to enjoy. As any cloud vendor, they now more about you than you might think of: your porn profile, you health history including all of your past, present and future diseases, what you're thinking about politics, products, people, or anything else, you whole set of social contacts, your wife and your secret girlfriend as well, and so on, and so on. Still don't care whether or not data like this gets exposed, archived, or leaked without your control?
