>What does Apple have a monopoly on?

This argument is so prevalent, but it needs to be unpacked: would most iPhone customers buy a totally different phone only to run an app that Apple doesn't allow? Whether or not someone can switch phones isn't really the issue, but whether or not the phone has replaced general-purpose computing and access to the entire software industry is the issue.

If Apple blocked Instagram I guarentee you hordes of users would switch to Android.

Buy Spotify is just another music app.
