Sorry, but do you have a source for this at all?

As far as I can tell, they have added some Play Integrity checks (with root detection being part of that), but the reason was cited as spam prevention, and I can’t find anything claiming they had any sort of agreement with Apple to do so.

They kept pushing for Apple to implement it, but I don’t know of any cases of them making any promises about what they’d do on their own platform in order to convince Apple or anything like that.
