Nowhere did I say anything about malware, abuse, or severe annoyance: you are taking a simple hypothetical and using an unstated extreme possibility to suit an unyielding position.
If a website uses one or two small, innocuous ads that aren't animated, I'd see no problem with it. You seem to be taking the extreme stance that any advertising at all is a personal affront to you. If that's the case, you are being unreasonable and such an opinion shouldn't matter to most people.
Now, it may be difficult to find an ad host that doesn't push giant, screaming, in-your-face ads, but that wasn't the point.
