Most companies don't have network effect with lock-in, and especially those we depend to live our everyday lives: I can send money to my buddy who uses a different bank, I can send emails to gmail users from my yahoo account , I can also refuel my car at any station and not be tied to one brand. Imagine being locked in to any of those.
There are of course a lot of companies with lock-in out there, but none with such big network effect deeply intertwined with peoples' communication and personal lives (in the US).
