I think we need a data Great Reset: all data (and I mean all) must be deleted by a certain date in the future, and all newly collected data must have provenance so in the future the customer can find out that Ford got information from Databroker A which bought it from B which bought it from Microsoft which collected it from what you type in Windows. Companies holding activity data without provenance get the crack-cocaine dealer treatment: officers in jail, everybody fired, investors and lenders fucked, company liquidated and forfeited.
While it is impossible to take back a disclosed secret, we can create a legal framework which issues immediate business-stopping corporate death sentences for spreading that data without consent (or after you revoke consent, yes it needs to be revokable). Your data is so valuable, because now that we have universal function approximators you can be simulated (to a prediction horizon) and that simulation interrogated.
