Isn't it, though? What's the copyright status of the output of these tools?

I'd love to see this go to court.
This doesn't affect what copyright law allows or does not allow.
Also I think Anthropic very much suppports gathering data by whatever means possible. That should work both ways.
Note that even in the normal case, there are restrictions. You'd have to validate that the generated output is not copyrighted. Which in this case may not be trivial.
