I suspect that this is the reason why Apple users complain about (even potential!) misfeatures to the extent they do. In the product categories where Apple is a player, from the standpoint of a dedicated Apple user, they have zero competition. All of the supposedly competing products are far below the quality-of-user-experience Apple users are accustomed to. Hence the perception that there is nowhere to run to.
Given how everything else you've said hinges on this assumption, you'd have done well to explain why you think it is true. Like I said before, you're conflating two markets.
As it depends on all players in a highly competitive market suddenly colluding to degrade the user experience upon which they all depend without anyone realizing that they might stand to make more money by not doing so, I find it hard to believe.
Try this on for size:
