The implication that vaporwave just up and died ("was"?) is bizarre, but I think I know why she says it.
I believe to many on the internet, vaporwave "died" when the masses grew bored of the meme they created out of it and had discarded of it like a child would an old toy. Because they treated it as a meme and not a real genre, they either never sought out more or didn't recognize it as vaporwave when they saw it (because all most were exposed to was Floral Shoppe, they think that's literally all vaporwave is, hence the "slowed down elevator music" meme). Thus, they think it ceased to exist.
Personally, I harbor no nostalgia for that time period (can
anyone be nostalgic for it? It was barely even six years ago when meme was big). All I really remember was lazy posts of roman busts with filters on them and excessive images of arizona iced tea cans superimposed over a windows 95 desktop. Not to mention all of the incredibly lazy attempts at making vaporwave that amounted to nothing more than literally just slowing down a random 80's song in audacity. I don't miss it at all.
Furthermore, "dying" was the best thing to happen to the genre. Because it forced many to re-evaluate what vaporwave actually
is and experiment more. Can't exactly have slowed down Diana Ross forever, now can we? In recent years specifically, we've seen an explosion of new ideas and styles evolving out of that rut, even getting almost entirely sample-less albums like Dan Mason's recent stuff and practically everything by Windows 96.

In conclusion:
Vaporwave is dead.
Long live Vaporwave.
(I hope I don't come off as elitist in those first two paragraphs. I only just realized after typing it all up that it could be construed that way. By no means do I wish to act better than someone for listening to such a niche genre of music lmao.)
