Valve could not stop the snowballing controversy any other way, so they have now removed the ability to sell mods on Steam Workshop. At least, it has been temporarily removed.
In a communuique, Valve admits they did not know what they were doing. We’ll allow them to sum it themselves:
But we underestimated the differences between our previously successful revenue sharing models, and the addition of paid mods to Skyrim’s workshop. We understand our own game’s communities pretty well, but stepping into an established, years old modding community in Skyrim was probably not the right place to start iterating. We think this made us miss the mark pretty badly, even though we believe there’s a useful feature somewhere here.
