> You have a problem with badly behaved scrapers, not AI.
And you have a problem understanding that "freedom and openness" extend only to where the rights (e. g. the freedom) of another legal entity begins. When I don't want "AI" (not just the badly-behaved subset) rifling my website then I should be well within my rights to disallow just that, in the same way as it's your right to allow them access to your playground. It's not rocket science.
This is not what the parent means. What they mean is such behavior is a hypocrisy. Because you are getting access to truly free websites whose owners are interested in having smart chatbots trained on the free web, but you are blocking said chatbots while touting "free Internet" message.
