The fact that they changed the original name of the trait was more insulting, but that is strictly my own personal opinion. They changed it because some people were offended, at least that was the impression I was given at that time. The icon is meaningless, since the trait was not orginally meant to represent what some people refer to as nerodiveginent.
It was meant to be a playful way to simulate someone who hears voices/talks to their different personalities like those are actual people. That is what those erratic emotional states usually represent. They don't really represent extreme mood changes, especially since the emotional states are way too easy to manipulate in-game. Btw, as a neuro-spicy person myself, the icon isn't a bother. It is just a silly picture that shows the emotional state is due to the trait rather than something like being in a "well decorated" environment.
I believe this is the case. I sometimes do not understand when people want Sims to be more like real life (adding mods that give Sims a mensural cycle and other real life issues that are usually beyond the Teen rating).
This is, IMHO, is not about having accurate representation of those with mental health issues—I wouldn't want a game to accurately "attempt" to represent that. I think it isn't meant—on purpose—to represent anyone.
But if I was to make a type-casted or stereotyped character like the Mad Hatter, the Queen of Hearts, etc. I'd not only want, but would need a trait like Insane for immersion. Straight-jackets I think are really only used in movies and series for fiction/fantasy storytelling, and are rarely even used in modern medicine anymore.
