This is not the Libertarian response. Google and Apple are now stewards of a captive audience--namely smartphone users. They possess a partial monopoly that should be unrestricted to competing products using their platform. IE vs. other broswers, etc. Sure they are free to censor pornography or offensive content, but if they launch a porn service and restrict others from offering a competing app in their marketplace, that could definitely be anti-competitive. Sure, users could flee to the competing device... but what happens if Google decides to do the same?
