What's that supposed to mean ? They don't have any monopoly, they are not even the dominant player in the smartphone market, and slipping in the tablet one.
I guess you mean they use heavy handed control on the apps they allow to run on their devices. But that's like its basic right. If you don't like the concept, don't develop stuff in somebody else ecosystem (i.e don't develop for facebook, google, evernote, dropbox, ...)
Ironically, if Apple was a monopoly, then the government could intervene on that basis. Outside that scenario though, I prefer to avoid shit companies on my own and not have the government regulating how the APIs to their service should look like. (disclaimer, I'm a bit sore on that point. Imagine calling Google Map api using EBMS and XBRL, that's the taste of Government Regulated APIs)
Now about "how they're a terrible company that doesn't really care at all about their users." That's a popular opinion those days, I'm only moaning about the monopolistic part of it (as its corollary, that somebody should tell them how to manage the plugins for their platform)
