A ton of news websites do this now, navigating to a “Before you go…” page when you hit the back button. I’ve always suspected this kind of behavior has a lot to do with why people don’t read articles anymore. You know what you’re getting when you open a comment section on Reddit, Hacker News, or Twitter. The majority of other websites are going to be borderline impossible to view on mobile.
Chrome with JS disabled works good enough for me on mobile. It's also easy to whitelist specific sites. But mostly, if I get a blank page I just go back.
