The Commission’s main concern is that iTunes’ current set-up in the European market prohibits users in one country from downloading music from a website intended to serve another country. Its move against Apple and the music groups was triggered by a 2004 complaint from a British consumer organisation criticising the fact that the UK version of iTunes was more expensive than Apple’s product in other European markets.This sounds like it's more a question of consumers' free market rights than an antitrust issue. I wonder what's going on here?
UPDATE It's competition (European for antitrust). Of course, the source for this story is... the story above. Hm.
