I've seen articles on NPR and Reuters that have brief summaries of edits at the bottom. Stuff like "Edited to correct affiliation of Dr X. The article originally and incorrectly said she worked at Y University." They'll also put an "edited at" time at the top.
Yes, those are good. But it would be so easy to have a GitHub-style change log, and/or a Wikipedia-style “talk” section where rationale for changes is discussed.
It could increase attention and time on the site as well, good for the bottom lines at the outfits too.
That's just dishonest stealth editing. Reuters in particular has been known to spread intelligence/CIA propaganda (particularly during the Turkey coup).
