We've lost a lot with the deletion of this repo. Not the code - that's already out in the ether - but the absurdist comedy of the issues, pull requests, and commit history of trying to piecemeal delete third party non-FOSS software.
The meme/troll issues were edgy teen style humor and not that funny, but the legitimate ones that tried to gently explain what rebase does and went completely ignored were funny because they felt surreal and hyperreal at the same time. Office-Space-esque comedy.
That's just the reality of any platform that doesn't gatekeep who gets to participate. Eventually assholes are going to join, that's simply unavoidable.
GitHub doesn't provide nearly enough tools for moderation though. Like restricting issue creation, comments, and discussions to only certain folks (beyond the per-issue controls).
