Surely you could just ..

Now do you still want to tell me that Google's absolute dominance in the search sphere is all that benign?
The fun bit is, of course, that most competitors are stupid enough to use Gmail, and so Google knows well in advance of any possible competition and either buys them or finds other ways to address the upstarts. Those of you old enough may have a feeing of deja vu here, as Microsoft was pretty much doing the same thing for many, many years.
