Bolded Point #1: Lewd models have been a thing for years. It's nothing new.
Bolded Point #2: This sounds like jealousy to me, but if it bothers you there's a little thing called muting Performance in your sound settings.
Bolded Point #3: This is false otherwise people would be getting banned as soon as they turn on any music related plugins or within a few days after using it. Clearly this is not the case as there are many individuals who have made in-game careers off of barding and continue to thrive.
Bolded Point #4: They have made a decision on it. They outright have stated that it's against the ToS, however they will not put anything on our PCs to detect what players are doing. This literally means: Hey we're going to say this is wrong but we can't stop you from using it unless you get yourself in hot water by using them publically.
Ultimately hun, your original post reads like you're upset that console players can't use mods or plugins and want them banned, even though if you were able to get a PC we both know you'd probably use them yourself. That's not the fault of the PC community that consoles are not able to mod (yes I am aware that Bethesda has done it in the past but they're a rare exception), nor is it on Square to level the playing field or pick sides and risk a riot by either side. Direct your anger where it matters, at the people who actually develop and produce consoles.
