It's different, because you can swap back and forth between Maccas and Burger King at will. But if you own an iPhone, you aren't going to also own a Samsung phone, so you can't swap back and forth between the App Store and Google Play at will. Yeah, sure, you can still go and buy a Samsung and have two phones, but 99% of people don't. Yep, it's not a super clean cut example of a monopoly, but it certainly is a monopoly.
There is an imperfect power tryst between "we the people", the government, and the corporate world. The corporate world doesn't get to do what it wants 100%, because at the end of the day, especially in a democracy, when enough of the "we the people" care enough about something, then our will gets done. Anti-monopoly laws are exactly this. You've gotta ask yourself, does "The Land of the Free" mean that capitalism rules and corporations are free to do whatever the hell they want, regardless of how much harm it causes to "we the people"; or does it mean that we are a democracy, and "we the people" get to vote and thus ultimately decide what are the laws of the land, and thus protect ourselves from being damaged by corporate actions?
