alt Hacker NewsFor me, when it specifically comes to copying, I don't think it's bad to copy a copier. (And by that I mean Anthropic has no valid complaints against Moonshot. Any valid complaints from anyone in the original corpus are valid against both of them now.)
In this way, it is different from literal theft. Stealing money/objects from a thief and keeping them is not justified.
It's a little different in this case, since 1) not all the data Ant used was stolen and 2) they did contribute significantly to the value of the stolen good.
An analogy might be a baker stole 20% of the flour used to bake their special bread, which was then stolen. Both thefts are obviously wrong and bad.
