Your theory is real but its not the main purpose, it’s a happy accident for Apple. Otherwise there’d be a class action.

I don't think so. There is always a cutoff for the last major version they recommend for any hardware. Why is the cutoff always after it lags the device severely and not -before- that happens?

I mean, they got a class action before for turning on CPU throttling after a major update without informing the user, to "preserve battery health".
