Wait a second, the requirement of a government to get a sim card is kinda standard practice in multiple countries. Also, when it comes to privacy, US based companies must be last ones to talk, like as if China is the only bad guy who infringes upon peoples right to privacy. China is dangerous, but it's not the only dangerous thing in the room. Also, your comment doesn't make sense. If you are committing your public credentials while diseenting against the government, you are doing it wrong. Also, any publicly committed credentials are like literally tracked by thousands of both within minutes. Its not like if China really want to scan them, they can't do it without Github telling them they found something.
