SlateStarCodex itself used to have advertisers on it, and the adverts seemed pretty much fine - just banners and descriptions from a bunch of sponsors, which were pretty relevant to the blog and, I guess, the people likely to visit it. Advertisement doesn't have to lie, it can just provide useful information you haven't seen yet. Although it generally does.
Advertising is like a stopped clock: even when they present some part of the truth, it's not information, because you don't know if it's true or not. You have to obtain information via other means.
And even when they make statements of fact, it's still lying because they leave things out with the intent to deceive.

That's the crux, though. It technically doesn't have to be like this, but it almost always is - so "advertising is a bunch of consumer-hostile lies" is a more accurate generalization than "advertising informs people".
