It's perfectly fair. When you live by the sword of proprietary and industry-unsupported protocols, you die by that sword as well. Apple products have faced this time and time again, with version updates killing 32-bit program support or pushing the OpenGL depreciation line. Because Apple doesn't have to compete on merits (as your comment points out), they just have to convince you to upgrade on a regular basis. Their routine depreciation and deliberate gimping of old hardware is evidence that Apple does not want you to keep using their devices once they tell you its time to stop.
