Plainer HTML and very little Javascript which will reduce development and running costs. As witness, this very website. It supplies all that is necessary and no more. It is very successful.

With harmful incentives removed, this would encourage websites to focus on good writing and less on being 'content farms' to drive up engagement for the advertisers.

All I want from most sites is the text. Not adverts, trackers and those damnable autoplaying videos that jump out and follow me down the page. I use the reader mode in most cases. Why is it necessary to use reader mode if not to cut the useless cruft? Why can't the web just be like that?
