The people who don't think React (or Vue) is important are the same ones who have never worked on a large project with lots of screen updates and state changes that absolutely cannot be avoided. React is still #1 in popularity, and the most crucial tool for almost any web developer (aside from using TypeScript, instead of plain JS which is also critical for large projects)
React is reported to be used by 39.5% of developers worldwide, while Vue.js is at 15.4%. The number of "apps" using just HTML+CSS is precisely zero, because those aren't "apps" they're documents.
