Well, while the market share is an important side note, the point is that they are a platform provider too. Microsoft had the problem a few years ago with bundling their Internet Explorer on Windows (and making it hard for the competition to have a chance). For Apple, the situation is a bit easier, as they don't allow any third party app stores at all, so any competition would probably encourage their users to break Apples 'Terms of Use', which in turn would make a lawsuit even more difficult. In my opinion, platform providers should be obliged to open their platform for all kinds of third-party services & tools but I am sure, Apple/Google/Microsoft/etc. will find other ways to discriminate others on their platform and push their services.
