We saw how laws completely failed to make encryption illegal in the 90s as open source encryption code spread rapidly on the internet. "Exporting" encryption software was illegal in many countries like USA and France but it became impossible to enforce those laws. A technical measure defeated the law.
Encryption is just maths. It is the law being unreasonable here, and it will be the law which will ultimately have to concede defeat. UK is the perfect example here - Online Safety Act's anti-E2EE clauses have been basically declared by Ofcom to be impossible to implement and they are not even trying anymore.
It's not your cat videos they're interested in. When people are protesting against the government it's vitally important that they're able to get information out as quickly as possible, to as many people as possible. If the government can slow that momentum down then opposition fizzles out. Chat Control would do a great job in service of that goal, it's large scale crowd control, not a targeted attack.
