Is this going to be fixed/known price? then you are describing "source available" model. I don't think we need another word for it -- it exists, and it works pretty well (even Microsoft uses it sometimes)

Or are you describing some sort of system where the authors get the fixed share (%) of user's company revenue? I think this is not going to work very well... just imagine a big company which is not focused on computers. Or a computer startup which wants to be bought by FAANG for billions of dollars.
