It seems like mostly a modern bethesda game issue. Morrowind modding (based on what I've seen) is pretty chill compared to the constant full on sneed attacks skyrim modders have when someone asks a question or nexus does something they deem awful (like add mod collections). Skyrim modders (and by extension fallout 4) have such a massive ego, they think themselves superior to everyone for some reason. Combine that with discord trannies and the monopoly they have on any form of large scale mod (getting nexus to straight up ban people who release something that they have already 'claimed) and you get a degenerate shithole of nothing being done, while acting like they are the second coming of christ.
Watching this happen is like yandere simulator, nothing is ever going to come of it. While skyrim modders have a hissy fit every time bethesda updates the game, because script extender cant automatically correct itself or support previous versions properly, morrowind modders just wrote their entire own engine. Although I'm sure all of this has been said many times before.
