Because you chose to present it that way in hopes of maximizing your revenue. Maybe you would be better off using a paywall. Personally, I don't think it's so simple in terms of all upside, since I may jsut as easily visit a content provider only to have my time wasted by copypasta or inaccurate reporting or whatever. Frankly, I would rather consume fewer products of higher quality, and am willing to pay not to have to look at advertising, but no simple mechanism exists for me to opt out from the ad-supported model on most sites.

Lets not specify any particular brand or types of advertising for the sake of discussion, all advertising is just advertising.

Not from my perspective. I'm quite willing to have products or services suggested to me in the form of advertising, but I'm not willing to be shouted at with garish visuals, distracting animations, or misleading taglines. I think there's a great deal to be said for the strict guidelines that Google imposes on adwords advertisers.

You may not distinguish between different kinds of advertising as a content provider, because the revenue it generates is fungible. I care a great deal about it as a content consumer because it imposes a time cost upon, which is highly variable depending on the content of the advertising.
