Consider that Verizon and AT&T, the two largest mobile phone providers in the US, are both Baby Bells resulting from the break-up of Bell Telephone Company in an anti-trust action.

The solution is to STOP the monopoly of Search
So that a new thing like Google Chrome can't happen i.e. Search can't be used to take over another space
