I guess the issue is how the ads are generated. adds generated on generic search terms are ok with me as long as they are well marked. ads generated on a deep and creepy level of privacy invasion, completely irrelevant to what I'm searching is not ok.
I'm content to live In a search world when I type "how to do xxxxx" an add for a software company that provides xxxxx as a service is the top two or three results. I'm not content with getting cold calls from salesmen 1 to 2 hours after I type in a search for gartner magic quadrant xxxxx. (this happens all the time)
if the ads served are keyword based on the current search, and clearly marked as add, I'm ok with it.
I even click on the ddg ads if the seem relevant on purpose, because I know it generates them revenue. I go out of my way to click on anything I know is a Google ad.
