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.
I'm extremely skeptical that this could be very effective for anybody who doesn't have a large legal fund (a license is only of value if you can afford to enforce it in court), but I'll keep some amount of hope anyway.
