I'm usually not the overly paranoid one but shouldn't you assume that all Chinese labs are training on your data no matter what the T&C say?

I would also assume the same for non-Chinese as well

The nightmare for Anthropic to be caught doing that combined with the temptation of their staff to virtue-signal by blowing the whistle...

I trust them to act in their own interest if nothing else.

And what if they use your data tò generate syntethic data to train on?

Not for Enterprise. You can safely assume the trillion dollar companies would ban GPT/Claude from being used in house if that was a concern.

I assume that all labs are training on any data they can get their hands on.

And American providers, not sure if it's still the case but OpenAI were doing this.

I assume that of all of them as a basic security precaution.
