Yes but then you aren't looking at the ad and from a marketing perspective that's not acceptable.

  Which is why it's good for marketers but not the user. I don't need to see the same ad more than once in a session but many video sites will display the same handful of ads every couple minutes. This is especially prevalent on twitch.tv when watching gamers stream, it's usually the same ad every time. After the first time I see it I'll just visit another tab while it's playing (mind you the audio is still playing.) If they were to pause while I was doing this I wouldn't bother watching at all.

  To move beyond the ad issue. Maybe I'm not interested in watching the video (say a presentation) but only listen to it. Then I have a legitimate reason for not wanting the video to pause: doing other work in other tabs.

    That's still not an argument for treating the possibility of detecting visibility as "user hostile"
