I'm not aware of any playerbases enforcing or even cultivating the belief that they should be the ones fixing the game. It's an interesting point you make though I'm not sure there's much of a problem, at least from the fans side in this community or any I'm aware of. If Bethesda for example are content to put out an awesome editor but fail to create a decent UI for PC, I'm not sure what the fans/consumers can do about it but what they did, complain and fix it themselves anyway.
Often people will just mention mods to offer consolation to those who are disappointed by a certain feature or lack thereof. For example in your thread about how stats should work the response wasn't so much that we can't expect the devs to produce a functioning, balanced and coherent game but just that development is virtually over and the only recourse you have if unsatisfied is modding to adjust the game to your personal preferences.
Mods are like the go to hope for any issue anyone has with a game really. Personally I'm just very happy that we will have a powerful modkit for this game, which gives us that flexibility to cater to our personal tastes and flesh out the game in interesting, unexpected and sometimes broken ways ;-)
If people were shutting others complaints down by saying, 'shut up mods will fix it quit whining' or something I'd agree there is a problem. I just haven't seen this happening myself though I'm not that much of a forumite so maybe others have a different perspective.
