You mean like Netflix making shows “second-screen” friendly? I doubt lack of focus ever really drove longer articles. It pushes them shorter and more towards bulleted lists and headlines only if anything.

[Insert ad here. Lol.]

Padding out the paragraph count just gives more spots for ads in between or more eyeball time for banner ads, and even if a site isn’t explicitly going for that, all the journalists (real or not) and LLMs are just trained to only write that way now.
