I think there's too much blame being placed on programmatic advertising. That's no excuse for 14MB pages, fixed position ads, trackers pinging the network for a full minute, etc.
There's no inherent reason why so much of the cost of ad networks, tracking (regardless of the arguments about tracking itself), and ad content needs to be born by the user. Better ad stacks should, and probably already do, exist, but it seems like most publishers and ad networks are lazy, incompetent, or both, and with iOS9 they'll soon see that they've shot themselves, and everyone else, in the foot.
