Source First License 1.1: https://gitlab.futo.org/videostreaming/grayjay/-/blob/master/LICENSE.md
This is a non-open source license. They were claiming to be open source at one point, but they’ve listened to the community and stopped claiming they were open source. They are not trying to be Open Source™.
They call themselves “source first”. https://sourcefirst.com/
They’re trying to create a world where developers can make money from writing source first software, where the big tech oligarchy can’t just suck them dry.
There’s no derivative licence that makes the source free to use but forces you to contribute (work or money), if you make money from it?
