Is it not because rent keeps going up while "entrepreneurs" use their work with minimal attribution and certainly no financial contribution to get rich? The same "entrepreneurs" who then act entitled to free support from the same developer struggling to pay the rent?
I think they're really just trying to solve the problem of "how do I afford to eat while still supporting software used by Facebook to make billions of dollars"?
I agree and can’t help but wonder if this is why we’re seeing more and more developers trying to make money from their Open Source projects.
