I think the worry is that we are already locked in and Facebook will turn into a Microsoft type company we'll be stuck with a system where it's very hard for anyone to compete effectively and innovate. You have to least have an account to find out what most of friends and family are doing, so not having an account is not really a viable option for most. Saying you won't have an account on Facebook, at this point is like saying you won't have phone because you don't like the phone company and that's ok because you can use some alternative that not connected to the system everyone else uses.
