LinkedIn from Microsoft locked me out — they demand I give my passport and access to my webcam to Persona

LinkedIn locked me out of my own account. The only way back is through Persona — a third-party service that wants a photo of my passport, a scan of my face, and a recording of my movements (liveness detection: turn your head, follow the dot, so a still photo can't stand in for me). The stated reason: "unusual activity." The real reason, of course, is big tech spearheading a movement toward absolute control over people.
