Macs today are not designed to be easily repairably but instead to be lighter and otherwise better integrated - I believe that is consequence of consumer preferences and not shady business practices.

As for the services - it is a bit off topic as I believe Apple makes a profit on their macs alone ignoring their services business. But in general I have less of a problem with a subscription / fee-driven services business compared to an advertisement-based one. And as for the fee / alternative payment controversy (epic vs apple etc.) this is something that is relevant if you are a big brand that can actually market on your own / build an alternative shop infrastructure. For small time developers the marketing and payment infrastructure the apple app store offers is a bargain.

Exactly what competitors products on the Mac don’t they integrate with? And no serious app distributes through the Mac App Store.

Both the Mac and the iPhone support standard Bluetooth protocols and USB protocols.
