I guess the Github Copilot authors did not handpick projects they checked were legitimately put on Github. So they are accomplices in that case.

YouTube doesn't really handpick things that get put on their platform either, beyond very basics and whatever automated tools they have to cover that.

Beyond that, that's what DMCA takedown requests are for. Github would only be an accomplice in that case, if they got a legitimate DMCA takedown request and chose to completely ignore it.
