As an example if I’m obliged to share my ID data via government to open a twitter account how would I know that the government would not link my twitter account to my ID and later use that info keep track of me and prosecute?
People would think that it would never happen, but not long ago that actually happened in East Germany. The Stasi kept track/files on almost every East German and this would be a digital version of the same thing
I agree that governments should minimize collection of their citizen's data. I just don't see where it is supposed to happen in this case.
There is no guarantee that the app would stay open source and under public scrutiny forever. Governments have done way shady things in the past. Given the recent push for chat control, I would never trust anything put out by EU.
