HTML and JS evolve very, very, very slowly compared to the needs of complex web apps.
If you're just building a simple page, sure, don't use a framework. But once you get into the realm of multi-screen async state sharing across components, a framework makes that a LOT easier to read and maintain.
At the end of the day the minor syntactic changes aren't much more complex than say, Markdown... they just facilitate component composition. The actual business logic is usually still written in plain JS. The templating language doesn't really matter all that much in the end, whether it's JSX or a Vue thing or a Shopify Liquid template or whatever.
HTML + JS isn't some golden standard that markup should aspire to... it is literally the lowest common denominator. It's historical baggage that everyone's forced to compile down to, and there's nothing magical or special about either writing in a framework or in pure HTML. Users don't care. Just make it work, and make it work within resource constraints. The latter is usually what drives framework usage... most teams don't have infinite time to reinvent everything in their own proprietary framework.
