What's to point of all this? Everyone will use Signal or some other E2E encrypted messenger, this is just bone tossing. Useless politicans spending time on useless things.
So the EU will just tell Apple and Google to remove Signal from their app stores and 95-99% of the population won’t bother figuring out it exists..
They are talking about mandatory on-device scanning. E2E doesn't solve this.
In every authoritarian regime people spent considerable amount of time on workarounds. Underground press, parallel education etc. this is just another iteration of Stasi like regime, just with a nicer suit and better PR.
In reality this should have been rejected wholesale and people proposing this barred from any public sector jobs, or even arrested for terrorist attack attempt (Chat Control fulfils definition of terrorism).
Chat control takes screenshots of your phone. E2EE is useless. It's government mandated spyware.
