Well, your post escalated to the broad claim that I responded to.

You didn't just disagree with AI crawler attestation: you're saying that nobody should distinguish earnest users from everything else because they should bear the cost of serving both, which necessarily entails bad traffic and incidental DoS.

Once again, services like CloudFlare exist because a cache isn't sufficient to deal with arbitrary traffic, and the scale of modern abuse is so large that only a few megacorps can provide the service that people want.
