Same problem on my web-site, where I research Amazon Redshift.

I've put up a username/password firewall - free, but blocks AI bots.

This has led the site to be almost wholly deranked by Google, but this is in effect what happened anyway, since the AI summaries were absorbing so much traffic.

This in turn leads to the next problem, which is that it seems now uneconomic for me to research Amazon Redshift. If I allow the site to be searched, AI bots will copy it. If I do not, Google will make the site disappear from search. At no point do I see a return on my work.

This means there will be no research in the first place, for the AIs or for normal people. The parasite has killed the host.
