I have a hard time believing that the radio select in YouTube's settings works, because I'm talking about dozens of videos, posted by different publishes, all of them with ads from the company I'm talking about. Maybe the publishers in question weren't aware of that setting.

Let me tell you more - I was visiting the US when the protests started and I posted YouTube links on my Facebook account, completely unaware that the videos in question were served with those ads, because those ads targeted only Romanians. The act of publishing a link is also an act of publishing. When I publish a link, I should be completely aware of what I'm publishing, OK?

Also, we go back full circle to monetization needs. I'm not seeing controls in YouTube for banning certain ads from happening. That radio select is a global switch. You either want ads or you don't. Also the question is stupid. Because it's an opt-out and if you are unaware of the setting, you're implicitly opted-in AND most importantly, that doesn't mean you'll receive any money from your views and likes [1]. Like, seriously?

It's an account-wide setting to allow the monetize option. From there it's up to the account owner to enable/disable per video they upload [1]. There are other things in place such as the ContentID matching which will disable ads until you prove you're allowed to use the content if it matches anything but generally speaking it's up to whoever owns the channel you're viewing videos on. They would almost definitely know they have ads enabled - there's even a green dollar sign next to the video in the manager if ads are enabled

Advertising-wise you can target pretty much anything/anyone Google knows really - You could very easily (It's one of the easiest options to configure even) target people in a specific country. There's more advanced stuff such as re-targeting people who have already seen the ad/content specifically too. I wouldn't be surprised if there was a way to target a specific channel or at least whatever common content is in each of the videos (the most notable mine name involved, for example).
