People seem to be raving about Skype supporting end-to-end encryption, and giving Microsoft credit. However, overlooks two points: (1) Skype started out peer-to-peer and MS centralized it, and (2) MS still collects metadata. I see it more as a MS's hand being forced by fact that most competitors are introducing end-to-end encryption, not because they want to add it out of the goodness of their hearts. Don't give credit where credit isn't due.
