Once I met a privacy advocate with a 30-year career fighting for privacy at multiple reputable privacy-first organizations who told me a database of medical records shared between the patient and their government satisfies his definition of a patient-private architecture.
Similarly, you will find many decentralization advocates claiming that many solutions, like Farcaster or BlueSky, are decentralized. They usually truly believe what they say, and that's why they are so effective in selling it, but the trick is to know what their definition of decentralization actually is.
