Some days ago,Indian government in a news report said about banning 14 chat apps for "promoting terrorism" in effect because apparently these apps have e2ee and that they do not have any representative in India who could be punished for not giving Indian govt a backdoor access, which by effect WhatsApp must've given.

So, today element.io started getting blocked for me. 10 minutes later, it was back and another 10 minutes later it was back down.

Here is the question , If a hostile govt wants to "ban" matrix network for example, how would that work on the ground? Would they manually ban each and every thousands of public and private servers? Clients?

Matrix at least won't comply so how?
