It's a fair bit easier to switch away from Google, as most of their services have much weaker network effects. For example searching, I can only resort to Google if everything else fails, and easily switch back and forth. (This is not to say that there aren't still tracking issues.) With Facebook, there is no alternative. If you want the value that the network provides you are trapped.
