There's a very simple, prosaic, explanation of the "foolish things": Apple employees need to make changes to justify their jobs. That's it. No changes, no job. If they can't demonstrate the usefulness of their current assignment, they might be instead tasked to work on the clusterfuck that is iTunes, err Music. Here's a simple pet peeve, it can best be explained as change for the sake of change: Open System Preferences. Why did the location of all the icons get shuffled around between macOS versions? It's no better now than before. But, hey, at least it kept the programmers from being forced to work on iTunes.
