It is only hypocritical when they bitch about things being unfair, or try to use copyright arguments in the court system.
Where else are you going to make those arguments?
Copyrighted works plainly have value for Anthropic. Why aren't they paying for that value?
As a vigorous, thrusting company surely Anthropic has the wherewithal to pay for it. And if they don't, if all they can do is steal, if all they represent is the theft of the labor of others, then what good are they?
Anthropic likes to talk big on ethics: https://www.anthropic.com/news/claudes-constitution
When will they start showing some?
I support copyright in a narrow sense, but I think it's proving to be increasingly archaic, conceived for a 19th-century world of mechanical printing presses and far too absolutist for the 21st-century world of memes, sampling, and LLMs.
