Did anyone else notice the pattern that ever since the LLMs got popular the "I hate javascript" kind of posts or comments have decreased?

It could be attributed also to typescript dominance of course, since people don't use plain js anymore.

As for the blog post, I agree, I also implemented my own js framework when I code in vanilla js and it works fine.

The problem is not inventing frameworks, the problem is that everyone invents frameworks, so people all know different things and they are hard to hire.
