Don't really know. Patronage seems to be working well these days. Lots of creators seem to be finding success on services like Patreon. Also, crowdfunding. There needs to be a way to get paid before you create it for the labor of creating it. The creators and their labor are what's valuable, not the end result. Data is infinitely abundant and trying to limit access to data is just insane. It's the 21st century and we have world wide networked computers capable of copying data at massive scales at minimal cost. Paying for data just doesn't make any sense. Once it's out there it's pretty much done.
