In some way it's similar to some of the provisions in the Digital Markets Act in the EU - when it comes to user's wanting to share data, organisations have to provide it to them for free; but if a company wants access to the data for their customers directly then there can be a commercial agreement and fee involved.

Think sharing your electricity usage with a company selling power solutions at home, they could get agreements to access this data on behalf of people using essentially peer-to-peer API services.
