There are some that do it terribly: Kursgesagt recently, Wendover productions (I hate deceptive segues), etc.

I guess it's a personal choice, but I prefer tracked ads that are properly labeled and not deceptive to integrated sponsorships and product placement any day. The real fear is that an extension like this will encourage even more deceptive and hard to skip sponsors (embeded product placement).
