There's been no significant litigation to establish case law on FOSS licensing. That's always bugged me, but I get it -- we behave as if the licenses are valid (and, yeah, I think so?), and folks who consume the code have mostly caved when threatened with lawsuits.

But now it gets interesting. Models trained on FOSS will do clean-room implementations of GPL code to get rid of virality:

I'm out of the racket, but somebody oughtta take this one to court.

@mikeolson There is plenty of case law (more so than every single proprietary license!).

And being trained on FOSS (copyleft? not?) cannot do clean-room by definition. The GNU GPL is also not viral, it is your choice if you accept it or not -- it does not, cannot, and will not "infect" your code.

The reason it is not taken to court is that .. you're talking out of your night cap.
