  > seems very unethical

I agree. Clearly Apple should do the only ethical thing and immediately ban all unsupported devices from new App Store purchases.

When Apple announces this (very ethical) policy change, I expect you to full-throatedly defend Apple from the mass shrieking cries of "but muh planned obsolescence!!" Right? Right?? ;-)

In fact, one could argue it's also "very unethical" for Apple to (negligently) allow someone to use a potentially unsafe or hackable product. To be maximally ethical, Apple should be remotely bricking any Apple device the day it loses security support. Better to be on the safe ("ethical") side and remote wipe too, to protect people's data privacy.

Can you see how Argument From I Merely Assert XYZ Is Unethical Then Demand Some Arbitrary Relief can quickly break down?
