It's clearly more than an interesting tech blog post written by one of the data guys in their spare time. It's an "initiative".

That said, this doesn't seem like completely superfluous "fat" like what Mozilla does. It seems very much targeted at generating interesting bits of content marketing and headlines, which should contribute to increasing Anthropic's household brand name recognition vs. other players OpenAI, as well as making them seem like a serious, trustworthy institution, rather than a rapacious startup that has no interest in playing nice with the rest of society. That is: it's a good marketing tool.

My guess is that they developed it internally for market research, and realized that the results would make them look good if published. Expect it to be "sunset" if another AI winter approaches.

Even on the contrary, this is very important information to have, in order to understand your customer base and how sticky you are with them, what features you need to focus on, etc etc
