> allows agents to act on behalf of registered users with economic incentives to control usage

There's a huge economy out there based on wasting human time. They explicitly do not want agents acting on behalf of humans, because it means human time is no longer being wasted.

They also don't want to get paid in money, because the money would go to a different profit center. The only payment they accept (because they use that as a metric to justify their salary) is "engagement" aka proof of wasted human time.
