It won't happen, but consumer protection agencies should come down hard. Even a class action.
If I have an old iPhone, I should be able to buy a new battery and expect the phone to more or less operate as before.
The fact that they are purposefully limiting the processing power of a device that was purchased to certain specifications is a gross abuse of trust.

yes that happened since my comment - good to see they are being made accountable.
