I don't quite buy into the public utility thing. Any Google product has competitors. The reason people use Google products is because Google advertises its new products on its products people already use massively. I don't think people actually see it as a public utility and are unaware of the competition. When you're in use-case A and suddenly you have a link from the same service to subscribe to use-case B, there's some effort required if you want to study the alternatives, and people prefer the easy way. Google crawls its way from one oligopoly to another this way.
