You're right if you're using the web in order to display content. That was the case in the 90s. In this case, yes, a simple index.html with a <h1> and <p> is fast, responsive etc. But with webapps being more and more common one could argue that displaying text is not necessarily the web's main purpose anymore. If you're trying to access figma with a text based browser it's gonna crap the bed, so it fails the test, but is it a relevant test though ? The web is bloated but it didn't bloated just because engineers were bored, it had genuine use cases where doing more than just displaying text was needed. And it wasn't ONLY for marketing purposes (but it played a big part i'm sure)
