No, this goes beyond that. A well-written article or book doesn’t need to be padded with junk to cater to bad readers, or to preempt trolls, because they can’t scrawl all over it such that it disrupts others’ experience. You have to go to e.g. the Amazon reviews to find people complaining that an author didn’t address something that they very definitely did, or claimed something they certainly did not, that stuff doesn’t show up on the page in footnotes or turn into flame wars on the page where everyone sees it.
