Unfortunately the choice isn't between sites with something like Anubis and sites with free and unencumbered access. The choice is between putting up with Anubis and the sites simply going away.

A web forum I read regularly has been playing whack-a-mole with LLM scrapers for much of this year, with multiple weeks-long periods where the swarm-of-locusts would make the site inaccessible to actual users.

The admins tried all manner of blocks, including ultimately banning entire countries' IP ranges, all to no avail.

The forum's continued existence depends on being able to hold off abusive crawlers. Having to see half-a-second of the Anubis splashscreen occasionally is a small price to pay for keeping it alive.
