2. Adverts only appear on YouTube for videos where monetization has been enabled or a third party owns the rights to the content. The description given by the GP post is somewhat misleading.
2. You're wrong. Monetization doesn't have to be enabled. The switch is in YouTube's settings and it's called "Allow advertisements to be displayed alongside my videos". That's not monetization.
I've also never met a single Romanian that earns money from YouTube videos. Google treats us as second-class citizens anyway (I still can't sell apps in Google Play btw). The clips I'm talking about have been in the dozens, many by volunteers, by different publishers, all of them with the ads in question. And as I was explaining in another comment, when I started distributing links, I wasn't aware of those ads because I was not targeted and publishing a link is also an act of publishing.
So yeah, rejoice in the availability of that checkbox. Everything is good.
