The first example is oddly specific. I think you can find flaws like that with almost any software or hardware manufacturer, regardless of monopoly status.

The second example is, I think, a perfect example of what most large companies do, which is to neglect specific features in favor of others. People want to work on the "new hotness" rather than maintain something written 10 years ago by a team that no longer exists.

I don't think either suggests that Apple software is getting worse as a whole. The simple fact that they rolled out an entirely new architecture and it's worked pretty flawlessly (except for some fraction of people when the battery drains to 0 and it hibernates and needs a restart) suggests to me that they aren't just resting and pulling in money based on their monopoly status (which they don't even have in any industry).
