Because you can’t use facebook and credibly make an argument about the importance of individual privacy. It would be like bringing a prime rib dip to a PETA rally.
Google is naked about saying, “Whatever you send us is ours” and then makes it so the ONLY way you can sync an Android is with their Google Docs Suite.

I just installed Do Not Track about three days ago and already have over 1,500 blocks! It is absolutely breath taking to realize the amount of information that has already been gleaned and cataloged and given to God knows who about my personal like and dislikes, where I go on the net and comments I made! I now have no expectation of privacy at all, anywhere. But at least I know who’s been watching me.
