Distillation may not be an attack, but it is a ToS violation and could be seen as IP theft.
Any reasonable company would be pissed if a competitor, especially at Ali Baba's size, leveraged that company's R&D to compete. It is in this sense, a corporate attack.
If you want to roll your eyes at distillation concerns, you might need to excuse Anthropic for originally using pirated material to train their models.
What IP? It seems pretty obvious to me that it's not:
So what is "IP" here?> you might need to excuse Anthropic for originally using pirated material to train their models
You have it backwards
More the opposite - companies who stole IP for their own benefit have no leg to stand on when others do it back. Personally I couldnt care less if Chinese labs rip off Anthropic. Its what America would do if they wanted to, for whatever reason (they probably do it right back secretly anyway).
