Social media and bank accounts are transparent by default. Individually, that may not feel like a major risk. The bank that knows your wealth probably is not going to rob you. Facebook reading your messages probably will not create an immediate problem for you personally. But the risk is at the aggregate level. A small number of institutions can see liquidity, sentiment, relationships, political energy, social coordination and emerging grassroots movements. They can trade against it, shape it, throttle it or intervene before it reaches critical mass. That creates an enormous asymmetry of power. “Private” accounts are not truly private when the platform itself can still see everything. A private Facebook profile is private from other users, not from Facebook. Nostr needs more read restricted relays and encrypted notes that only the intended audience can see. Something closer to a private social graph, without a Facebook like entity sitting above it all. Privacy is not just about hiding individual secrets. It is about preventing aggregate surveillance from becoming a control system.
