Generative AI is a major setback to OSS licensing. I've been on projects where we needed to do a "cleanroom" implementation and vet the team has never viewed the source code of competing products. Now in the gen AI era, coding agents are IP laundering machines. They are trained on OSS code, but the nuances of the original licenses are lost.
On the whole, I think it is a net gain for civilization, but if we zoom into OSS licensing... not good.
