Interesting. So is the goal of regulation to ensure it's easy for people to switch "towns"? What if Apple, Samsung and Google needed to make it simple and easy to switch between their respective platforms, to a best effort? For example, if they both had similar cloud photo storage they would automatically exchange those. In other words, if we can make switching mobile ecosystems as easy as switching stores then we shouldn't take issue with Apple or Samsung or any other mobile platform. Market forces alone can influence how each company runs their business.
I don't know about that. How is this different from Costco selling a membership for a year? You've just paid up front for access to Costco for a year and now you are "pretty much locked in". Why doesn't a cookie company sue Costco for better placement the ability to pay for those cookies with cash directly to the cookie company? Those poor customers are locked into Costco and have to live with Costco's choices on which products to stock, where they go in the store, and pay for them through Costco checkouts.
