I don't think there has to be an ulterior motive to this sort of policy, they have decided upon a set of rules to build their community and that is it.

And persons with theories about how socializing on the web should be, start chiming-in as they chose this pseudonym topic to publicize and unfold their theories and criticisms. They can go elsewhere to be as pseudo-anonymous as they like, I recognize that pseudonyms have legitimate purpose but all this self entitled rhetoric is just trolling.
