> What’s the incentive for people to allow the crawler at all?

So that LLMs can learn from it? Profit is not the only thing that motivates people. I’ve spent years contributing to Stack Overflow to help people solve their problems, with the understanding that they had an open data policy and anybody could access the data dump easily to build things with it. It pisses me off that they are now trying to lock that information away where LLMs can’t access it. The whole reason to contribute is to help people. Locking that information away instead of exploiting this new channel to help people more effectively is antithetical to the reason I contributed in the first place.
