I'm not so sure that Google actually does have the same circular monopoly power as Apple, because really it's just about lock-in and - from experience - moving from Android to iOS is really easy. You don't lose any data and everything is cross platform by default. Going the other way by contrast, you'd have to deliberately move things into third party cross platform apps.
I'm also not sure whether that would count as a monopoly if they did have sufficient lock-in, given their vast market share - as a hypothetical. I guess probably yes.
I'd agree that neither should be investigated, but I do disagree that Apple have as much grounds to be - they just don't have the market share.
I was probably too simplistic on education, it's a difficult issue for sure. My ICT teacher in school used to have a pretty big budget and spend it on toys because he got Windows hardware/software so ridiculously cheap. Microsoft had made the ICT curriculum in the UK entirely based on learning how to use their software and apps. All their stuff can be obtained between free and really cheap for students from school to university, and it's pretty much always the standard expectation to use it. And then you have iPads and Chromebooks taking over, probably not running Microsoft apps and probably like you said with no real plan. It's interesting and probably broken, but there's probably no monopolistic player there.
