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:

  * trademarks (not using the mark)
  * patents (what patent?)
  * copyright (the code and models are all different, and machine outputs lack creativity and are not copyrightable) 
  * trade secrets (any member of the public has the same access to input/outputs. They're not accessing any secret)
So what is "IP" here?

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).
