It is about the law, though. Proton has always been clear about the possibility that they are required to hand over data if the Swiss government requires it: https://proton.me/legal/transparency
So IDK where you are getting that they are saying one thing and doing another thing and even more important where you got that they shared ENCRYPTED data. Cause if they have the ability to even do that I have to rethink my choose since that should be impossible if Proton did it correctly and are trustworthy.
Yes they did because most countries have some form of agreement that they share data when legally requested. It is pretty hard to bypass that, but it is duable (Mullaval VPN f.e.)
They didn’t just surrender the data, they started collecting it at first

And let me remind you that there is a non-profit above it and they need to handle for the purpose that was created which is still Protons core businesses. They make more money just doing whats right than not because otherwise people would go back to something free or go to Tuta/Mulivad
