I remember a few years ago AdSense was showing a lot of fake Download buttons (and users would complain about it). I haven't seen them recently, though, so I hope that means they've fixed that problem.
EDIT: I guess AdSense is involved with AdChoices somehow. My mistake.
The AdChoices icon is used by many ad networks, not just Google's, to indicate that there's per-user targeting happening. [1] But if you click on that "AdChoices" button and you get an AdSense help page.
The link from the ad is to https://googleads.g.doubleclick.net
I don't see how it can't be a Google-sold ad.
I suspect the reason that kind of ad is allowed (despite being deceptive IMHO) is that it's not just a download link. It also indicates that it's an ad for a driver update site (which makes it even shadier to my eye, but probably not violating any policies).
That post is from 2013. The answer to the question in the title is apparently "not for at least three years".
I'll take Google's concern about deceptive ads seriously when they stop serving those ads themselves.
