Meta doesn't operate in China though, for not wanting to comply with their requirements of state-controlled censorship. I could see them applying similar reasoning here on principle (my god, I just used 'Meta' and 'principle' in the same sentence, I must be high). Another tech company might jump in that hole of course.
With regards to E2E, I wonder how it would work when you want to chat with someone outside Belgium though. If I'm the person outside Belgium, I wouldn't want E2E to be disabled just like that. And if WhatsApp can only be used between Belgians, that's quite a hinderance.
Belgium doesn't care about Meta revenue and rightly so, but if a law would be the reason that Meta pulls the plug on Belgium, that seems like a cause for a possible serious political backlash.
I wouldn't give FB/Meta _too_ much credit. I'm pretty sure they would comply with China's regulations if they were able to. It seems much more likely that FB cannot effectively moderate the amount of content people post and cannot comply.
For your second point, to me that's the same kind of feature work GP was talking about: Just add a little UI that says "Hey, you're speaking with someone in a country that doesn't support encryption. Your messages are unencrypted".
Also agreeing with GP, screw Meta! As a Belgian I could care less about one company when it comes to the rights and laws of my country. They can definitely make suggestions like everyone else, but they also need to follow each country's laws like everyone else.
