here is the difference, if you don't like google, don't use it, I don't. Don't buy Apple products if you don't want them to have your information. With the government though using its services is not optional. Facebook could ban you or block your content if they don't like your speech, that's fine its their site and being kicked off won't hurt you. You have no right to Facebook and Facebook can't throw you in jail. That's the difference.

A lot of people could choose not to use facebook and then they would cease to exist or become the next Myspace, not so with the government.
