Wouldn't such language and reasoning from Anthropic be an argument that they needed written permission to train their model on data from websites?

Has any individual somewhere around the world tested this in court by now? Sued Anthropic for copyright infringement because Claude can reproduce information that is only available on their website?

It shouldn't be that expensive, right? If you sue them for - say - $10000 then what would the costs of such a court case be?

Personally, I think "learning" is not a copyright violation. But if they themselves make it one, then they should also face the consequences, no?
