At the Linuxdays 2019 in Graz I gave a motivational talk "How Do I Profit from Free and Open Source Software?" as I already announced.
It is be a motivational talk that mentions some arguments for free and open software. I tried to cover the point of views for normal computer users, companies deciding for software or source code producing persons deciding for a license model.
Due to technical issues with room speakers, the whole talk was suspended from minute 32 to 36. Please do skip the time in-between. You do not miss any content from the talk since I stopped talking until the issue was solved.
You can get the video also from the CCC media server which I recommend in contrast to YouTube.
