Apple, I get it. I get why you do it. But seriously, this retroactive punishing of prior 3rd-party purchases is asinine. I had purchased multiple lightning cables from Anker (a very reputable brand), and had one of the iOS 11.x updates basically render them useless. Apple's product support is not fast enough, nor pervasive enough (to say nothing of cheap enough), to justify this behavior. Edited for clarity
