Does the author dislike react? How about preact? Or maybe simply jsx? Or nextjs?
There's nothing wrong with either of these if used correctly. Thus "hate" is a rather shallow argument.
I will safely assume the author dislikes all that overly complex bloat bullshit and leave it at that. I am not going to autism this, as in invent a bunch of straw men to attack because there is some singular obsession silo of react-like fixations.
Your argument that it’s a shallow argument is itself a shallow argument. ”I hate x” is not a technical argument anyway, it’s an emotional assessment.
