Claude being a official contributor here gives me the shivers. This feels like setting up a case for: We have the rights for everything you do with Claude. Or rather what they do with Claude for you.
I'm just annoyed that they treat it as a person. Claude isn't a contributor more than that shovel I used to dig a hole in the ground is. Even if it's a really good shovel.
In that case they should cite every author of every source used to train their model that enabled this result.
