There's nothing inherent no, just that javascript webpages, if some CDN doesn't load fast enough, or the dev uses some bleeding edge function not in all browsers, etc, will not end up having the text in the page. Whereas actually having the text in the page always has the text in the page.

JS sites almost always fail very badly when it fails (a relatively common event). Text sites cannot fail even when they fail.
