No it doesn't. Most projects are MIT or some other permissive liscense.
Exactly, most projects have a license of some kind, they aren't "free-for-all-do-whatever."
MIT requires attribution. Forcing enforcement of this cannot be done without copyright law. You can argue that attribution is stupid and nobody deserves credit for their work (which might be increasingly true in a post-LLM world), but you can't speak on behalf of all projects that chose those license and say "it's what they want!"
