I pay for the ad-free tier but I still get ads for their live streaming service (and for their DVR, every commercial break gets replaced with 3 minutes of non-fastforwardable commercial content), which is why I'm probably going to stop using their streaming service. I really only wanted it for sports channels anyway.

I think this must be show-dependent. I, too, pay for the ad-free tier, and the most ad-like thing I've seen is a 2- or 3-second Family Guy is returning on <date> and a FOX logo interstitial at the start of streaming an episode of Family Guy. Can't recall seeing anything else across a number of shows.

It seems to be network/show-dependent. The ad-free package removes all the ads that Hulu shows, but if Fox has ads of their own they're still in there. I usually get a single FX show promo in every Simpsons episode I watch.

I have no idea. Sports events tend to be hours long, and every commercial break has these. You can technically skip a few minutes ahead, but then you miss part of the game.
