I see a lot of misguided comments blaming Microsoft for this when it was actually one of the advertising agencies they contracted with, Starcom, that created the problem. Companies use influential You Tubers all the time to promote products. If they are compensated to promote a certain message that is being presented as opinion they must disclose it to viewers. If you don't and get caught, this is what happens.
