I'm not sure whether you can actually do that. The law works on provenance, not on bits.

There are techniques for reproducing copyrighted code in a legal way. The simplest one would be to simply remove all the copyrighted content (assuming it came from minor contributors) and clean-room a replacement.

The clean room method breaks the provenance.

This is not just writing stuff from scratch like all of us have done at one time or another with our own code.

Maybe they can use GitHub's Copilot to "rewrite" the code :)

Didn't racket do much the same with their switch over to mit?
