I doubt it's about price gouging -- Apple makes most of its money selling phones, tablets, and computers, not adapters and accessories. Sure, you could argue that they're trying to lock their customers in by getting them to invest in tons of adapters and accessories that would need to be replaced if they switch to another ecosystem, but I think iOS and the App Store ecosystem are much better at that. Besides, why would they keep changing port designs every few years if lock-in was the goal? There's no better time than a port redesign to switch to someone else's hardware if you need a new device and have to buy new accessories anyway.

USB C seems like the future for basically _all_ ports on all devices, so I do think it's a shame that Apple's going to stick with Lightning for iOS devices. It's hard to blame them for this -- Lightning is quite a bit thinner[1]. But I also don't share their obsession with device thinness.
