If individuals are going to produce full campaigns with 20+ hours of play using D:OS assets, I don't believe monetisation should be allowed other than donations. However if some are willing to produce their own assets (models, textures, what have you) in order to create new campaigns or areas, then I think that much more effort and planning would be put in, and would deserve (not mandatory) payment.
Given the choice, PC gamers and mod users largely do develop an etiquette within their communities and I reckon the standard of donating to more professional mod authors would arise here also. At the end of the day, mods = choice, take away our choice to experience mods freely and plenty of people will just end up forking out for potentially sub-standard 'add-ons'.
