> There's no other word for it but "insane". They can engineer their A-series and M-series microchips

There are certainly other words for it. Lazy, anticompetitive, disinterested, any of those are more plausible than all of Apple being insane. They sold you a microchip that you knew you wanted, now they are beholden to little else. For over a decade, Apple didn't even offer the iOS APIs for third-parties to implement cloud storage. They know you need their software services, regardless of how shit they are.

Insanity would be a pretty satisfying explanation. Fickleness fits a lot better with Apple's track record though.
