google, who works harder and harder to sell everything I do to advertisers (now you can't even rate apps w/o a google+ account), and who just shut off transmitting search data so they can screw site owners for more $?
microsoft, who is a party to this and actively worked to make the internet worse (and succeeded!) for the better part of a decade?
or apple, who at least isn't run by and for advertisers?
all choices suck
