Most news sources reporting on Apple are American: MacRumors, PC Magazine, Slashdot, Engadget, Ars Technica, Macosxrumors, ThinkSecret, CNet...all of these are US-based. Reports coming from the United States would be written in American English, just as one might logically expect.
There are plenty of reputable international news sources, but when you're reading an American technology news source reporting on an American company, expect to hear American terminology. It's as simple as that. There's no anti-UK (or anti-anywhere else) sentiment behind it.
I have lived in five different countries and represented dozens of non-American clients, and I find it both offensive and baseless to argue about American stereotypes, which you've decided to run with for no apparent reason. Moral of the story: don't read American news sources, misunderstand the language, then refuse to accept the explanation when it's offered, and finally claim that your own misunderstanding makes the people who offered nothing but an explanation somehow bigoted.
