It's uncontroversial that with high traffic websites these sort of frameworks are necessary, but the decision to use React is much more commonly being applied at tiny companies as the new "right way" of building things.

What is unclear is what you lose by not using React. This is similar to how trendy MEAN was back around a decade - "it's web scale", etc...

This gets into necessary versus unnecessary complexity, which is nuanced. But the large scale companies get this, and are doing just fine handling it. It's the small ones that can't draw the distinction. Discourse on these sites or articles is much more likely to matter to these smaller companies, and so in general the best "universal advice" is probably to recommend the simplest thing that doesn't close any doors.
