If I felt that people should give me a cut of any commercial software they build on top of my library then I would try to express that in my choice of license.
Though we as a community can still have views regarding kids hacking things trying to profit off decades of hard work by a large community. Different if they contribute back obvioisly. There are lots of compromise models out there.
Edit: Softened unreasonably provocative expressions
And the mask slips. Maybe don't gatekeep software using licenses as they are designed to be used
Though acting legally and acting ethically/responsibly are still different things.
You did read the rest of my post right?
