You can not call yourself a privacy project and rely on githubs good will!
I agree with that statement. It’s strange that some privacy-oriented projects are on Github, letting the user browse and downloading files from there via clearnet, letting Micro$oft track every IP/cookie and all.
That said, when “something bad” happens, it’s probably not as simple as that source code is banned. Like, they did attack Tornado Cash yet they didn’t ban source code (which is after all free speech).
If you’re planning to self-host it only for one year, perhaps you’d be survived by Github anyway. Though again, I do agree with you that Github is not certainly the best place to use.
