I think the point is people should use the correct tool for the job. Instead, sites that should (or can) be static sites are unnecessarily using some JS framework.
Newer JS frameworks like Svelte and SolidJS can be almost transparent to the user, though - with no need for bootstrapping a complex codebase in the client before they can interact with the site. I'm guessing that OP describes a further development along these lines.
i think you're conflating static sites with sites that lean heavily into JS frameworks. plenty of sites are not static, cause they need that whole session thing, and don't use JS frameworks
