This is such a unfair interpretation, it's a false equivalence argument. "OS X added Terminal and throwing out HIG for a UNIX-y UI" is a moot point.

It's not about loyalty, it's about Apple's own coherence and vision as a creative-technology company, and a bunch of sophisticated users offering a critique of it over time. Read it that way and it makes a lot more sense.

Beneath the Apple "fandom" or any fandom there are valid reasons why they came to be (the quality of the product), and we ought to elevate that than call customers naive for not adopting the very corporate cynicism that is a result of anticompetitive economics.
