As a French citizen who's been building an open source Dropbox alternative for almost a decade [1], the sovereignty talk in France makes me cringe. Everyone has the word in their mouth, but nobody bothers to even search for alternatives, let alone give them a chance. France represents about 1% of my customer base with only a single customer: LVMH. I've had a whole bunch of French universities contacting me, nobody was willing to contribute toward the development because culturally we assume libre software must be free of charge so you'd better either beg for grants or have a rich uncle to sponsor your life. I've tried reaching out to the people who talk loud about sovereignty. Turns out it's just something they say at conferences to entertain each other as they have no power to actually make it happen, and don't even get me started on public markets.
