I always did apache, I think AGPL would make it less useful for the honest people and the AI companies would find a way around it. Companies in foreign countries would still get it and then the companies here could get it from them, or something like that. They're probably already trying to figure out a way to obfuscate when the LLM directly copies from a licensed codebase. And there's that site that rewrites GPL repos so they can be used commercially. On top of all that I don't know if it would be possible to sue companies that have been given de facto legal immunity to steal IP.
