It works sometimes, and Proton did not stop providing services there, you can buy their vpn, the government just blocks the protocols.
The US has a law that may require you to add backdoors to your software. Do they have to comply with that one in your opinion?

Seems you are confused how those blocks work so let’s talk about their services that are definitely not blocked like mail. You can easily and legally buy their mail service in those countries. Do they have to comply with their laws with their mail service?
Didn’t understand your answer about the US laws. If some judge in the US decides that Proton need to make a backdoor, what happens then?
