Yeah, I am no fan of proton and they have lied before (no log VPN logs magically finding logs for authorities and then later removing the no-log claim).
But this is literally just proton being legally compelled to hand over data the user willingly gave (not being harvested or de-encrypted). A nothing story.
It is always great to warn people against bad European companies too. We have plenty of people and companies who are as bad or worse than in the US.
Nestle is objectively one of if not the worst companies in the world apparently devoted to almost exclusively doing evil. Spotify is also terrible, Unilever had done some bad shit apparently, our many of our auto companies are also not good, etc... Many of our companies would literally kill to get American labor laws here and have spent billions Union busting and lobbying/bribing against workers.
