I think it's not the devs, but the managers who push the devs. It usually is. In Apple's case the managers want devs to desperately keep everything in such a a way that it only works with Apple, cant work with anything else or we might lose a customer! It probably won't have caused this particular problem, but you get the idea.

I somehow doubt they have the same people building online apps and the designing processors.

I have a dormant apple account for I had an iPhone before. The annoying thing about that account in particular is that I need an apple device to manage that, so without it I can only hope to remember that password correctly. But setting this aside, that iPhone was a neat little phone and I do miss it at times.
