Apple was also in a fundamentally different market position at the time. so, it's a hard thing to compare to honestly.i'm not 100% on the details of this but i think steve jobs was able to thwart an anti-competitive investigation by basically saying the competition sucks (adobe flash) and would result in a less-than-perfect user experience on ios devices..
something like that
when the iPhone was released in 2007, and generally for the first few years, Apple was a "small player" in the mobile field. yes, the iPhone shook things up, but it wasn't till the 3gs that the iPhone took a dominant market position.
Part of anti-competitiveness is the ability to use your dominant position to abuse competition. they were hardly in that place back in 2007. 2015 is a completely different ballgame however.
Is Apple being anti-competitive by monopolizing App store software distribution on iOS devices? YES
is apple being anti-competitive in the entire global market by doing so? No. they are not the dominant player (sure, biggest single phone producer, but worldwide, iOS is not dominant)
so, in reality, people don't like it? Change platforms. This is probably why the FTC is taking such a while to decide to persue or not, because unlike microsoft in the 90's, wich 95% of the desktop market, Apple is generally sitting at < 50% of the phone market.
