Netflix puts the ads directly inside the shows they control themselves. This way no adblock can censor them, and Netflix can prance around pretending they are saints for not showing ads. Example "Hey let's call an uber" says character A. "I watched X on netflix yesterday" says character B.
You choose the shows your kids watch; you don't get to choose what commercials a cable/airwave channel shows you.
I’m so accustomed to Netflix and it’s child controls that I totally forgot what legacy tv is like.
