Yes, it seems that Google is held to a completely different standard than their competitors. Google open-sourced Android, and now competitors like Amazon build Fire Phones and Fire Tablets. Can you imagine the same openness from Apple or Microsoft? Google allows alternatives to the Google Play Store like Amazon AppStore. Apple and Microsoft are locked down. Apple won't let you create an app that competes with Apple services, but Google does. Apple and Microsoft default their maps and other apps. Microsoft defaults Bing as the search engine on mobile and desktop, and Apple requires a billion-dollar payment to default Google search on iOS. Where is the anti-trust action against Google's competition? Think about why there might be a double standard here.
