If you read the fineprint, they all say mostly the same variation on "we do not train foundational models on your data". That is not to say they won't train other models, or use signals to train other models. It's just the data that doesn't get copied to the training set. And this makes sense. You train on your own data, and use the signals to know if your run was good or not.
