Earlier quoted context omitted.
'bother' me? No, not at all, the sounds are close enough I get the meaning, mostly from context. I am not sure why there should be an emotional factor here, as expecting everybody to conform to some pronunciation ideal they have no experience with is arrogant, to say the least.
Well you claimed that Americans are pronouncing it "perfectly correctly," and Germans might disagree. It's a German word which has been Americanized. The company mostly doesn't care, but there is a single correct pronunciation in their native language. Insisting you are correct mispronouncing a foreign word because the letters look a certain way is just hubris.
But see, that's the point. We're not speaking German when we use a borrowed word in English. It's no longer a purely German word, despite its origins, just as "xylophone" isn't a mispronounced Greek word, nor "Handy" a misused and miscapitalized English word.
That's not hubris, it's just descriptivism.
