Seeing as the question posed out of "[honest curiosity]" to someone else is then immediately answered by yourself host without you even pausing to put on a sock, I think your honesty is very questionable.
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...?
Attribution is certainly polite, and I sorta doubt Anthropic of all groups is intentionally witholding it for h-score or prestige, but that's all a much lower-stakes conversation than potential license violations. AFAIU.
