Optional
And that seems to be the key. If something has options, it's less a monopoly. You can put Linux on a PC. You can attempt WINE etc.
You cannot put even Lineage OS on an iPhone (unless things changed recently).
I mean, the dedicated can run Windows 95 on an Apple Watch. But for consumers, there is little choice in who to pay, and what price to pay for what type of product.
I think Apple only got away with it for so long because they are the hardware providers, unlike MS with windows who allow a lot of 3rd parts hardware (understatement ;) ).
Now people realise, it's similar to John Deere and right to own/repair/use as you see fit. Apple arbitrarily blocking others is not helpful to the consumer. A "trusted bit" (similar to Samsung Knox IIRC) would allow Apple to have their cake and eat it. They get security, secure enclave etc etc, and if you user wants to install their own OS/App store, then Apple could theoretically drop those services they cannot guarantee with others software.
