And you're also okay with Valve and Bethesda taking 75% of the profit straight out of those mod authors pockets without having done a goddamn thing?
Would you not agree that a donate or tip jar system from which all or most proceeds go straight to the modders and where people can choose to pay how much they want after thoroughly testing the mods would be a better system?

Kinda seems to me you've missed the actual reasons people are pissed off.
