Break Google up.
Shatter it into separate, distinct, individual, independant entities that must compete in only their specific market against others willing to fill the power void. Google Search, Mail, Maps, et cetera, all sliced off & forced to run on their own. No cross-pollenation of employees from one department/unit to another, the employees from each unit are fired from the main Google megolith & rehired by the individual department/unit that applies. Tack up a giant sign in the office of the Federal Trade Commission to say "Never let Google recombine!" & then *enforce* that edict.
Google - you're Evil & need to be broken up like a cheap boy band never to rejoin forces.
