You're usually not the one deciding which stack to use and evem when you are, if you don't use the latest shiny framework and put it on your CV, you're not getting your next job.

A big problem is also support by libraries. Back in the day, you could find dozens of libraries to do what you wanted and they worked regardless of your stack because it was all JS anyways (the exception were jQuery plugins, but jQuery is pretty good about not fighting native APIs, so you could still integrate those even if you weren't using jQuery elsewhere). These days, it's pretty hard to find modern libraries that just give you a CDN URL and an init function - most don't even build shippable sources because they expect you to use webpack or whatever, not to mention, that you can find the exact same component ported to Vue, React, Angular etc. but very rarely also to "native DOM", for lack of a better term.
