Not just news sites, either. A lot of fandom wikis run on the same platform, fandom.com. That site is a pain in the absolute fucking ass to use on any mobile device, specifically because of the autoplaying video that takes up half the screen on every page load. Weirdly, desktop is fine; no autoplaying videos or any such nonsense. It's only on mobile that Fandom has seemingly made a deliberate effort to make the user experience as frustrating as possible. And not once has the video had even a tangential relationship to the article being viewed.
