All these cutesy insider pronunciations only serve to confuse and alienate the uninitiated, it's elitist nonsense.
I don't fight my colleagues when they say "Suss" rather than the correct pronunciation of Suse Linux, because when it comes down to it, language is just an agreement that certain sounds mean something to the group that they are being spoken to. There's nothing inherent about the sanctity of language. If you can't be flexible, you might not be cut out for it.
I was doing Qt development in the 3.0-4.0 timeframe (3.x was release, 4.0 was in beta) back in 2004/2005 when Trolltech was independent and I attended a Trolltech sponsored conference at which all the "Trolls" called it "Cute". You can't pin this one on Nokia.
FWIW, despite knowing the "real" pronunciation, I refuse to call it anything other than Q-T ("Cue-tee") aloud
