Re: How many webasters have control?
Actually most outfits big enough to have their own sales operation have a reasonable amount of control over the behaviour of the ads on their site. The reputable ones will also have dos and don'ts and red lines (we certainly do), and you've even got some control of what comes in from ad networks, in that if you find an ad unacceptable you can tell the network you don't want that ad again, or maybe you just don't want that advertiser again.
What you can and can't tell them to do, of course, relates to what they want and what the market as a whole is prepared to accept. And what you might deem acceptable doesn't always match what the readers deem acceptable. Bandwidth is a trickier one to define rules for, and I doubt very much that the advertisers are currently prepared to accept limits, although some of them will listen to arguments about massive loading times. But I don't think anybody's whacking you with 40 gigs per banner, so it's seem to me it's a loading time issue, not one of cost.
Google makes the most money because of huge volumes, incidentally. Its ads are actually pretty inefficient by everybody else's standards, and while I hear and agree on quality, Google really isn't the benchmark.
As for the lying publishers that several of you have touched on, it seems to me that this assumption is built into the proposal. Practically all publishers will say their ads are not intrusive, sure, but if you disagree you block them. The point of the proposal is you are presented with the choice, not that the publisher gets a get out of jail badge. It really is not the guy's intention to give site owners control, quite the reverse.
