Nobody is saying that, you're making a straw-man argument.

People are just saying that they have no interest in being part of a network that tracks their videos, location, actual name, phone number, text messages, behavior across the whole internet, email address, and builds a psychological profile on them in exchange to look up college buddies (and therefore have deleted their accounts).

Many of us want a network that errs to the side of too private, and it's okay if not everybody is on that network. Many of us would rather have no network as compared to one that's too public.
