Oh sorry, I must have misunderstood! My bad, honestly; I was under the impression that GPL vs. MIT was about copyleft stuff, which would seem to preclude Anthropic's use of that project altogether. Not 100% sure how it relates to attribution still but I'll have to look into it I guess.
I don't really understand what was "answered by [my]self host" nor what a "desite for exclusion" means but it seems beside the point I think. Also not sure what the alternative to curiosity is. Like, I'd be trying to entrap this prestigious researcher in some legal sense...?
