This is quite problematic area indeed. If developers are happy for receiving 500$ for decades of their work, what justifies paying more in the future? I guess everything is good and there is no need to change anything. I get it, that it is the idea of open source, but the demands are increasing towards authors while they just use their spare time in most of the cases. More of their work is used to generate money, but authors are receiving barely anything.
