On principle, I do NOT agree with this. For me, I just want the experience to be decent. I understand that everyone has different tolerances towards ads (length per ad, how many total # ads there are, where they get inserted, what they are.. especially political ads, how often they repeat the same one). For me, Hulu is a prime counterexample where even if they, paid me money, to use it... I wouldn't. Let alone if it was free.
As for what we refer to as "double dipping"... they've run some expenses and determined that ad-revenue alone isn't enough for some of these services. Not like why some business venues have a cover charge. Or why despite how pricy some Apple products can be, basic accessories and other stuff costs extra $$.
