I hope they do get sued! As I'd love to see how this goes. What happens when everyone just points their claudes at specs and outputs and *doesn't look at* the source code? Is that still a derivative? Or a reimplementation? If latter, is license relevant? Software licensing gonna be get fun!

That's a different question. What's relevant here is that every AI has trained on Git's code. So it's not being reimplemeted without looking at the code.

I am not at all sure the legal system will rule that outputting a new implementation "from memory" of git, given a spec and all of the training data which went into them, is a violation of the data it was trained on. There are some cases before SCOTUS this summer (?) which might change that though.
