That's not how GitHub works
Blocking someone on GH doesn't lock them out of a repo, they can still fork repos, sync forks, etc. You just can't submit a PR, issue, comment, or some other community interaction. This isn't preventing devs from getting updates, that's fear mongering
This is getting insane.
Godot isn't just blocking devs on Twitter, they are blocking them on GitHub, preventing them for getting engine updates.
