I suspect this is more reflective of a scale issue than a direct decline attributed to the capabilities of the company. I suspect that when a company reaches a certain amount of market penetration where the number of active users reaches into the 100s of millions, that number of eyeballs over that many devices begins to show the cracks which maybe got glanced over previously. My comparison for this is, of course, Microsoft. As they were coming up, we were forgiving of their set-backs, but into maturity, people started looking for alternatives, their had to be something better because their stuff was SO buggy. I point to the Vista 'fiasco' as an example. Was it really a 'fiasco'? Or was it just that, even when what was considered a small number of people upgraded, and recognized issues, that small number of users was so large that it brought major attention to the issues. When 10% of your users have issues and you have 10 million users, that's 1 million voices. When 10% of your users have issues and that's 100 million users, it's considerably larger. Diversity of hardware platforms further exacerbates this issue. When it was just the iPhone1-3, the hardware wasn't considerably different. Bring on the iPhone 3, and increased pixel count, and you start to notice a few more minor issues, then iPhone 5 with different screen layout, handled well by apple, but not seamless. Now start adding some devices having fingerprint scanners and some without, some with health data gathering and fingerprint scanners some with one of these things, some with none. Sure, you 'should' be able to test for these small differences, but it gets considerably more complicated with each iteration. Apple has done a good job of getting people to retire old hardware, or not cause a fuss about not being able to upgrade, but they're still getting into a realm of device numbers they hadn't experienced before.
