I can't remember ever hearing anyone mention privacy/data control issues outside of HN. Facebook has ridden slipshod over these issues many times and yet I've never heard anyone bring them up in conversation. The echo chamber here is booming with concern but who actually cares? Users care about the communication advantages of their online accounts but how many value the identity associated with them? People change their phone number because they want a new model that isn't available on their network. Do they see their online identities as any less interchangeable? If this is the case what kind of explicit threat could possibly justify paying money for protection of such an identity?
