lol I remember loving how new and fresh TDA-style Miku looked when it first came out and now it looks god danmn awful and overused as fuck to me.
Tbf those Japanese modellers always seemed that possessive over their assets, it’s a strange reality where they have circles of hentai doujin artists with lax copyright laws over fan work yet I’ve seen how protective they are over this MMD shit. I know that, but I can’t explain it.
If I were to try and relate I guess it’s like every model being a tribute piece to the character (let’s say, Miku). I’m not saying Western fans won’t put all the time and effort that goes into making a model (with no pay for that matter), but the Japanese artists have this respectful undertone to their idolatry.
Then to take this piece of the character and put it in a known meme factory where people will be people and make the anime girl say "FUCK, SHIT, POOPEE” with her middle finger out seems kinda..... no.
Plus these models are often professional in quality and they probably don’t want their assets plugged into a free game where the data will likely be passed around like herpes like any game developer. They also don’t want to play tech support to the next person who doesn’t yet understand ‘no we don’t make things for a game we don’t play and no we’re not open for offers’.
I might be wrong because I’m not a nipland native but I try to understand it as best I can.
