More and more sites are having to set up defenses from AI bots. It is costly to provide online services and they were not built for bots.
One can say that the AI companies are performing a global denial of service attack, which incurs costs to all of their competitors, as well as the rest of the Internet, while their own services can afford to withstand that load. The service owners are forced to perform costly operations to defend them selves, but also make the services worse for the users.
This is anti-competitive.
