Assuming they did then they surely paid for them, which makes it "not stealing". Am I also "stealing proprietary U.S. technology" by harvesting my Claude chats from my `.claude` directory and training a bunch of models on them?

That said, I doubt the "they distilled Fable" is the reason why K3 is as good as it is, considering the timelines involved, and that Anthropic hides thinking traces, and their overly aggressive "safety" filters.

This constant FUD spread by Anthropic is so tiring.
