You mischaracterise me. I am an Emacs user and I use qutebrowser as my web browser, which uses Vi-like bindings and Python configuration. When forced by circumstance to use other browsers, I use browser extensions to add Vi-like bindings. I find it extremely efficient and enjoyable.

The keybindings aren't mentioned in the "Why?" section of this blog post, and clearly aren't the point of the post. You can get extensions to add Emacs bindings to full-featured browsers, and there's even the Nyxt browser which has Emacs keybinds and Lisp configuration.

The core reason listed in this blogpost for browsing this way is the very fact that it is less featureful and less convenient. As someone who uses Emacs, I know that eww isn't as convenient as a fully-fledged web browser and I know that sometimes the hard way of doing things can be beneficial. I found this blog post disappointing because it doesn't afford you any new information, nor tell anyone about any actually useful features about browsing in eww.
