Didn't know about this, glad to know others are seeing a similar problem! I've definitely tried to monetize self-hosted projects that could benefit from Fair Core in particular.

The flexibility of the licensing text is also nice as it'd be very easy to modify the standard "two years to open source" timetable or drop in a different license type like GPL:
