Monopoly or not isn't necessarily the question... In the EU the issue often seems to be abuse of market position. If Facebook were to lock Apple users out of new critically important Instagram filters because they wanted to sell the FacePhone.

IMO, these things are hard to regulate, and most of our walled gardens are surprisingly interoperable :)
