Im not an expert on these things, but I think there is another type of attribution, that I guess is what the commenter is more concerned about, and that is academic attribution. It is part of academic culture that you attribute significant influences in the articles you write. There are no licenses as such for this, as far as I know. You do it because that is what you do in academic circles. If you dont, you are not in the club.
I am certainly biased by a passionate distaste for IP law in general, but I am honestly curious to hear the reasoning behind it in this case.
In case it helps: this is a "research prototype", so I'd assume that seeing one or more aspects used in a highly impactful paper would be about the best possible outcome. Is this about publish-or-perish stuff, perhaps (e.g. citation "importance" for the algos)? Or maybe you're okay with this in general, but are regretful because it's Anthropic in particular?
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.
It’s still early days, true, and courts may find legal reasoning to address this... But I fear this stems from a fundamental yet little-known flaw in copyright for code, based on a legislative hack, which can only be made worse by caselaw. I ranted about it a few days ago: https://news.ycombinator.com/item?id=50320875
