I think most people arguing against react are against "advanced" ui libs at all. simple dom + a thin porcelain like htmx does help you finish most work duties without having to add a whole paradigme over.

And anecdotally, if your team is not ready/willing to dig in react, all its benefits will fail to materialize, you'll have a bunch of patched up libs and components trying to do what htmx or similar seem to offer (async actions over REST) for just a few lines in your html template.
