If this is where the things are going the time may soon come for someone to launch a GitHub clone that deliberately only bans illegal content and provides technological means of protection against Twitter mobs.
Meanwhile, it would be nice to have a reusable code of conduct written with the same attitude. E.g., it would only forbid personal attacks, credible threats of violence against other contributors and violations of the law (like committing warez to the repository). It would deny any responsibility for what the contributors say elsewhere on the Internet and state an unwillingness to discuss their speech on the project grounds. It could include anti-blackmail clauses like that agitating people on social media to "support" your issue by shaming the maintainers will get you banned and the issue closed immediately and irrevocably. The latter would have to be carefully written, though, to not be exploitable.
