If this does bypass their own (and others') anti-AI crawl measures, it'd basically mean that the only people who can't crawl are those without money.

We're creating an internet that is becoming self-reinforcing for those who already have power and harder for anyone else. As crawling becomes difficult and expensive, only those with previously collected datasets get to play. I certainly understand individual sites wanting to limit access, but it seems unlikely that they're limiting access to the big players - and maybe even helping them since others won't be able to compete as well.
