All you need to do is watch my parents use the internet (Google search and adsense laden sites) to realize that a HUGE portion of Google's revenue is based on tricking non-geeky folks into clicking on things that they didn't know were ads. While the right-hand ads are somewhat clear, the top ads (nearly white, right near the #1 result) are NOT and novice users when routinely click on that ad when asked to click on the first result.

Adsense advertisers are constantly rewarded for walking the fine line between blending in and just outright tricking their users.

While maybe this isn't outright EVIL, it certainly is disingenuous.
