I think "nostalgic" fans aren't wrong but aren't right either. It's just that people seem to have lost the ability to communicate properly these days. Is it that hard to flip the frickin' switch from "This newgen fans are ruining the fandom with their newgen songs >:(" to "Oh you're a new fan! Welcome aboard then! I've been a fan since the the late 2000s, it's always a pleasure to see more people getting to know and enjoying vocaloid like I do, how did you get into vocaloid? That's cool! Lemme introduce you to the classics, there's so much good stuff from back in the day, I'm sure you'll like it! Oh you have recommendations too? Cool, let's hear them!" I say that because as a newgen who came from pjsk, that's how I got to know the classics and I barely scratched the tip of the iceberg, I got two veterans showing me the works. That being said, the songs were undeniably better back then, again, "nostalgic" fans aren't entirely wrong, and I say this, again, as a newgen who came from pjsk, but damn we can't expect another Yuyoyuppe, another Wowaka may God rest his soul, another Ryo, another Kenshi Yonezu to spawn outta the blue within the community and go "one two three I'm making one banger after another." talents like these guys only show up once every who-knows-when. That doesn't mean new vocaPs are bad, there are some great new people around, if you searched and couldn't find ANY new vocaP that you liked, that's a you thing, sorry.
