After many years of decreasing usability, and increasing-user hostility, the same annoyances making the mobile web suck have wormed their way into the desktop experience.
You know what? I’m just closing tabs like this these days. I don’t even care to find the buttons that close the interstitials, because I know I’m going to get more of them, and some gods-forsaken unrelated video is going to start playing, despite all the protections against it that are supposedly built into Safari. Just forget it.
