"It’s faster, simpler, and better for everyone."

For who? In the modern day and age most devices can handle some JavaScript just fine. The DX provided by front end frameworks/libs is just unrivaled. Vanilla JS/jQuery work fine for small stuff, things quickly get out of hand in complex projects, when you have to bake in things like UX, validations, and have to program around the limitations of HTML. I'm confused as to why make such a claim as "Don't do SPAs for websites" and then throw in a dumb broad statement like "Just do vanilla". Yes, you can use CSS and achieve a lot of complex functionality. Yes you can use the existing HTML tags for a lot of things. Is it more maintainable than just using React? No.

You can't live in a silo. Yes, if plain HTML works for your website, why bother with anything else? Just do forms for any submit, input validation, there you go. But for a company competitive in the industry, particularly B2C SaaS, UI/UX does matter. And lagging behind, more than a trend, means customer perception.

We tend to be biased in our takes as tech-literate people (I do), but the average person gets lost if a button isn't emphasized enough.

A lot of website-in-spa break basic web stuff that simply works in old school HTML. It’s possible to do all that stuff correctly in react, but vast majority of people working on those simple websites seem to not give a damn.

Vast majority of information/portfolio websites have best UI/UX with classic HTML with some JavaScript sprinkled on top where it matters. Nothing says competitive-in-the-industry like contacts page that takes ages to load.

How? I spent 6 months exploring React, Vue, Node, Next,...

The DX for all of them sucks. The documentation sucks. Everything is wrappers of wrappers of npm scripts of wrappers of bootstrappers of boilerplate builders of...

Seriously. The worst.
