The file linked in by OP, is the main argument by Pawel Jarczak why his fork does not violate any copyright laws (may it be written by/with help of AI or not).
Personally I found the article (not the tweets) much more useful to understand the context of all this, as someone very out of the loop. Certianly more useful to me than a long list of very specific, in my option largely LLM output, points about a codebase I'm entirely unfamiliar with with claims that seem to need a legal team and court case to be meaningful. Slop is somewhat unfair and I'm happy to be disagreed with.
