I don't know about the top people but Anthropic has always been pretty deeply linked with the effective altruism/AI risk/TESCREAL memeplex. IIRC one of OpenAI's people who's pretty prolific on Twitter weighed in a while back to the effect that Anthropic mostly sees themselves as an organization dedicated to serving Claude. Not serving like server but serving like... worship. I find them a little freaky to be honest.
