Don't forget that a lot of trust was destroyed with this action (between mod users, mod developers and game company). It will take a while until it is restored again.
Because of the strict rule no commercial mods rule that Bethesda had in the past, the community adjusted to it and made their own set of rules and principles. These where endangered. Sure it is easy to say that it is only the greed (mod delvelopers wo want to make money, mod user who don't want to spend money) but thats actually not the main reason for the backlash (at least in the view of mod developers who are against it, I am one).
These principles are a very good thing and has lead to astongishly great results when a mod developer asks for permission to use the assets of another one. Both share ideas and techniques and both learn from each other that way. It worked so well that the mod user nearly got commercial quality (even above). Asking for permission is a simple pm.
But as soon as it is businesss.... then you have to negotiate and look that you get the best money out of it... modmaking is horrible time intensive if you are serious about it actually you can't pay these countless hours in a fair and balanced way sadly imo.
Thats why it isn't easy to establish something that at least gives a tiny bit of compensation. So if Bethesda want a way to increase the use of mods and increase the quality they should start supporting the mod community a bit more directly. It started well with Skyrim it got a lot of more support as the Fallout series (updates of CK, original developers answering question and are available,...). From a commercial aspect before Beth really can think anout monetization it has to be easier and less time intensive to make high quality mods but thats a tough nut to crack (without to simplify the game itself).
