I love that there is a lot more enthusiasm about OSS adoption within EU software devs, but at a population or government level there doesn't appear to be any coherent strategy to gradually replace US tech other than these knee-jerk headliner moves that don't move the needle much.
As a software consumer I would love it if there were open-first software standards adopted within this large of a population that would force US Big Tech to actually compete rather than rest on their monopoly power. But I am pretty skeptical and pessimistic about this actually being able to happen, given the historical failures of the EU.
In the case of ffmpeg, about a decade ago, I worked at a company who made substantial contributions to it, and employed many significant contributors. You guys live in fantasy land.
Linux is also an American thing. The benevolent-dictator-for-life of Linux lives in Portland, OR. Intel (also in Portland mostly) is one of the largest contributors, along with AMD. We can go on and on. this is obviously going to be the case when the main CPU vendors are American.
