Shoutout to Basecoat UI[1], so implementing the same components using Tailwind and minimal JS. That's what I am preferring to use these days.
in my anecdotal experience as a bit of an old fogey with a greying beard, the enthusiastic juniors come along, watch a video by some YouTube guru (who makes videos about code for a living instead of making actual software) proselytizing about whatever the trendy new library is, and they assume that it's just what everyone uses and don't question it. It's not uncommon for them to be unaware that the vanilla elements even exist at times, such is the pervasiveness of React bloat.
IMO software education/tainment suffers much worse though. They teach you how to do X in only this specific way with these specific tools, generally sponsored. Not the admittedly far more boring basics to do it yourself, or how to actually use these tools in a broader sense.

I call it 'Shiny Object Syndrome' - Frontend devs tend to love the latest new JS frameworks for some reason. The idea of something being long running, tried and tested and stable for 5-10 years is totally foreign to many FE devs.
Despite its age JS and its ecosystem have just never matured into a stable set of reliable, repeatable frameworks and libraries.
