I think an unsung hero in making open source broadly known and adopted in France is Framasoft [https://framasoft.org/en/], a non-profit association. They have since many many years an initiative to de-google internet and provide free and hosted alternatives and resources.

The French have amazing technologists, I worked with many stunningly brilliant French men and women across 3D gaming, film and media production. However, culturally they end up in a little "French pod" when not working in France because they know how to and really enjoy vigorous debate. If one cannot hold their own in their free wheeling intellectualized conversation and debate style, one might end up feeling insulted and stop hanging out with the frogs. There also seems to be a deep cultural understanding of design that is not present in people, generally, from other nations. That creates some interesting perspectives in software interactive design.

France has always been super heavy on open source. They even used to host Les Trophées du Libre, international open-source software competition. FramaSoft (i.e. PeerTube) and VLC are also French.

Isn’t VLC French also?

You have not been paying attention.
