First, these statistics are for phones shipped, not current active users of said phones. It's well known that iPhone users tend to hold on to their phone for longer before upgrading compared to Android users, who often switch phones much earlier. You need to look at operating-system market share based on active users(e.g. web tracking), not "who upgraded their phone this quarter". In that regard, Apple has over 56% market share in the US and over 24% market share globally [1]. Secondly, the fallacy here is that people, like yourself, keep conflating the smartphone manufacturing or operating system markets with the individual software markets that developed around each platform. Mac software doesn't "compete" with Windows software because people tend to have one device or the other. That software is what makes the platforms themselves competitive between each other, yes, but the actual software industry that's dependent on them is not competitive across those platforms. They are competing with apps within their particular platform, including the purveyors they have to go through (e.g. Apple and Google). You wouldn't say that the Bear notes app on iOS is competing with the Scarlet Notes app on Android because they're in different markets. Instead, Bear is competing with Apple Notes. Even if we are to go by your 14%, that's 14% of 3.5 billion people. IMO, that's such a large amount that it should be considered it's own market, but that has to be determined by a court. No one is arguing "monopoly" of mobile smartphones here. They're arguing a monopoly specifically of iOS software distribution. The Microsoft case wasn't in relation to other web browser developers, but of other operating systems and of manufacturers because they leveraged their market share to illegally maintain their monopoly in that regard. Their monopoly was their monopoly of the Windows operating system, not the Internet Explorer web browser. What's being argued here is that Apple is leveraging their power, or distribution monopoly, over the entire iOS software market, not "smartphone" software in general, to gatekeep competition of software and software distribution while also profiting from that gatekeeping. This is going to come down to how a court interprets this because antitrust isn't as cut and dry as other areas of law, especially now that individual markets are not so easily distinguishable in the current tech world.
