If you're technical this stuff is super easy to get around if you care enough. Realistically this will only be enforceable if the application has enough users and there's a company that owns the application which can be sued.
The answer is largely going to be to just use open source software which doesn't have CSS and continues to implement E2E. For work I don't care because it's not my privacy to protect so I'll probably just continue using whatever – Mac, Slack, etc. For most personal stuff I use Linux anyway so I don't really care.
Something I will warn people of in advance is that if you're in the EU/UK people have been arrested for terrorism simply for their book and memorabilia collections. If you're suspected of terrorism (at least in the UK) you do not have a right to silence and this extends to being legally required to hand over passwords/keys for your devices.
Once CSS is in place if you have any edgy Alex Jones memes on your phone / computer or a digital copy of something like the anarchistic cookbook don't be surprised if the government suspects you of being a terrorist or if you get put you on a list.
CSS and breaking E2E gives governments everything they need to find out who all the wrong thinkers are in society so they can protect us. It would be irresponsible of them to pass up that opportunity. Keep your opinions to yourself, and ensure all jokes and memes viewed or stored on your device are safely within the Overton window.
