What about the (large, I would argue) slice of parents who want to let their kids watch TV but don't want them bombarded with ads for sugar-saturated foods?
(I mean, we're on HN, so the obvious answer is watching things on a laptop / projector with Firefox + uBlock Origin, but y'know - everyone else).
Those parents need to find solutions that don't involve forcing their morality on others. Thats how we get xenophobic and homophobic people voting to control women's bodies because they think others should do whatever they believe is moral and right.
