Rescuing the morons from themselves...
> I think you're missing the point. The billions of desktops don't know how or don't desire to switch engines tomorrow, that's the problem!
That's simply not Google's problem.
There's simply no technical or structural barrier keeping customers in place. The fact that most people are apparently too stupid (your own observation) to choose Pepsi over Coke is not a problem that should be solved by the government punishing the victor. If they are doing something like dumping, or even like what the article said (hiding competitors), that's something more along the lines of classic anti-trust.
The fact that most people buy Cambells, Ford, and McDonalds is not an anti-trust issue.
Search is a commodity. It's not a platform that requires buy-in from 3rd parties. So conflating Google and Microsoft is grossly misleading.
