I'm comparing content to content. Yes, some is media rich, but if I want media heavy, I'm likely using Netflix/Youtube or similar anyway. If I'm using a web page, I actually actively don't want media heavy content.

And you can get graphic novels on Kindle nowadays. To pretend it is just text is to undersell the formats now. Could I claim they are bloating? Certainly. Still have a long way to go before they reach current web browser bloat. Which only seems to be marching on. With no signs of restraint on what to pursue.
