Yeah, I also hate back-button hijacking. I suspect some websites do it to artificially force more page views for ad revenue. Try a long-press on the back button to view the history for that browser tab and click on the most recent page you think won't redirect.
Usually with this, it's like 20 entries, so pushes everything else off.
The ones where it's only a couple entries mostly seem to be the ones where there's multiple articles on a single page and it's at least might be attempting to be helpful?
I recently looked into this after it seemed like Facebook messed with my back button on a private mobile window:
Someone pointed out that it's nice to have, for example, your email provider know that you probably want to go back for a message to your inbox instead of going back to the previous page.
But what if browsers monitored which sites abused the feature and showed a pop-up when you click the back button, just like they offer to show you notifications? They could show you:
This site has been reported to hijack the back button. Would you like to go back to the last domain that you visited?
Youtube does it, and it just continues to blast the wrong video you accidentally just auto-started because instead if fucking off, it shows other videos with the bad video getting just reduced.
