It'd honestly be pretty alarming. They just took the entirety of the internet to become rich, and now that they have something to take, they intentionally worsen the whole thing (by investing additional training data) to ensure resellers/ distillers get worse responses.
I'm obviously not taking the side of the resellers here - if their T&C don't allow reselling, then by all means restrict their access. But intentionally training the model to give worse responses when it sees a specific date format, would be pretty messed up.
