I agree, Google needs to be very careful where they go from here. If they try to take over Android, or the iPhone, or the world, they could get into a shit load of trouble because of the antitrust laws in place here in America.
It's pretty ridiculous that a company can get in trouble for providing so many great services for free.
It's not that ridiculous. What happens when they decide the great services shouldn't be free anymore since there is no competition. Even Hayek hated monopolies and argued that rules and government intervention were needed to defend against them.
They can integrate themselves into their products (positive efforts) but they can't block their competitors in any way (negative efforts). Takeover just has to be totally positive.
