Talk about the a false equivalency. Google owns their web site and search results. Apple doesn't own the mobile apps in the app store, at least until they change the developer agreement to say they do.
A real equivalent would be if Google said that anyone who wanted to show up in their search results had to use AdSense or they were banned from the index. People would be outraged, and rightly so. The FTC/DOJ would come down them very hard if they ever tried anything like that.
