Oh I doubt that very much. Ads can only blame themselves for acquiring that "evil" reputation, no need for shaky speculations. You have to remember that Adsense is actually one of the most appreciated type of ads out there, because it is textual and on topic.
For most of the world, ads equals constant annoyance, loud tackiness and profound stupidity with a message of materialist lifestyle and artificial needs. Just turn on your TV or the radio and you'll see what I mean.
As a finance source, ads can also be blamed for corrupting many things and influencing what can be said or not.
