Software Freedom Conservancy: Give Up GitHub: The Time Has Come!

The threshold of originality is not a single character, and almost never a single word (you have trademark for that), and rarely a single line. If you type "for (" and it autocompletes to "for (i = 0; i < n; ++i) {" is that copyright infringement? It's a non-trivial question how big a snippet needs to be before a verbatim copy is infringement. It's not that black and white.
Even for larger chunks, with the usual example being the fast inverse square root - but that snippet has been copied so many times in so many places, it's almost folklore now. And in all cases I've seen someone was _intentionally_ steering the autocomplete engine toward that answer. Would it pop up in a completely unrelated case when not actively trying to make it appear? And would a copyright lawsuit from the original author based solely on that snippet win a court case? I don't know, I'm not a judge, but it's really not as clear cut.

Certainly less common large verbatim copies should not happen, and the team was adding some checks for that IIRC. There might even be a config to disable that from happening now?
