So, power gets his way. He's created a world in which the kid doesn't watch videos, for now. The world in which he does has been smashed, for now. Power wins.
But what if the big man puts his weapons down, sets out to avoid bullying? What if he decides that when he wants the little one to do something different, he'll force himself to come up with something interesting. The kid eats too much sugar? Make him something healthy and delicious. Don't know how to? Figure it out or the kid eats sugar. Outcompete the sugar, or lose. As for outcompeting videos, start tickling, make cardboard robot costumes, playforts, etc. If that's too hard, leave the kid to his videos.
