Does the presence of adsense cause readers to leave?

Tweet

Something that was mentioned in another conversation was that according to one responder the presence of adsense on a blog caused him and his friends to leave and not read a blog. The implication was that the mere presence of adsense indicated that the blog was "for profit" and not worth reading. This comment has been nagging at me since it was said. One I don't make any money off of the adsense on my blog, and two I have tried my best to keep it relatively unseen on my blog. On the other hand, I am not above accepting income if it happens to occur. So if you are looking at new blogs, does the mere presence of adsense make you quit reading? Or was this person the exception rather than the rule?
