I thought the issue people have with AI scrapers is the ones that DDoS sites to scrape everything for training purposes, rather than the ones that interactively query specific content to support an active conversation?
First one is problem because it brings no traffic back and occasionally DDoSes the site
Second one is problem because it DDoSes the site. "Just" queries for hundred thousand people (if you happened to be good source for that bit of knowledge) that don't bring actual people to your site is also a problem
If you read the article, you'll notice that they're explicitly making sure to block the ones that interactively query specific content too.
