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.
I don’t think this protects us. I view the “encryption is maths” position as referring to backdoor keys.
But this time they figured out client-side mandated spyware is a viable way of breaking e2e without contradicting mathematics.
I hate to get dystopian but we can all see where this is going; “Trusted Hardware” is mandated to run your Government ID app and Untrusted Hardware is illegal because it’s only for criminals and terrorists. Your Trusted Device performs client-side content scanning, it’s illegal to install an untrusted app, and all app developers are criminally liable to monitor for Harmful Content on their services.
This is what we are fighting against. They keep trying and they are getting closer to succeeding. And none of this is incompatible with mathematics; it’s a pure rubber-hose attack on the populace.
