They are the ones that might currently do less than the other two, but history shows that giving one company too much power means it will be abused sooner or later. Google seemed a really, really nice company in the late nineties. When it developed, people were fascinated. When the first versions of Android came out, I was coding like a crazy, happy to own an "open phone" I could simply copy MP3s and ebooks to. And look what a monster they became. Now I do whatever I can to get rid of Google from every aspect of my life, and believe me, it's not easy at all.
