You've got a point there, but I don't see this as a huge deal if they don't begin to abuse their position. Which they might, but I'll reserve my judgement until there's something to judge.
FWIW, I would argue something similar wrt the Apple tv: abusive practices or not, I would not be happy to see one of the world's wealthiest corporation become a key player in yet another market (if anything because of Apple's sketchy history wrt to open formats).
