A correction because there is a lot of miscommucation being spread - primarily by Chesko who is doing damage control.
"I am also considering removing my content from the Nexus. Why? The problem is that Robin et al, for perfectly good political reasons, have positioned themselves as essentially the champions of free mods and that they would never implement a for-pay system. However, The Nexus is a listed Service Provider on the curated Workshop, and they are profiting from Workshop sales. They are saying one thing, while simultaneously taking their cut. I'm not sure I'm comfortable supporting that any longer. I may just host my mods on my own site for anyone who is interested.
Is very misleading by Chesko. Mod authors have the completely OPTIONAL ability to say hey would like to donate a small percentage (think it is like 1-5%) of their money to Nexus. It is entirely up to the mod author and a way to say thanks to Nexus. If they don't do it Nexus gets nothing.
DarkOne, whom I often don't agree with but do this time, explained it as did others. Chesko is dealing with major backlash and is striking out to make it seem like he is the victim (which he is to some degree but it isn't the fault of Nexus).
I am trying to avoid the whole thing myself. I won't be paying for mods as I think this is a bad move and my own content will always be free (what little there is of it). I also don't begrudge people getting some coin for all their hard work. But I do dislike it when people give false and misleading information.
