This take shows up a lot and it's a bad one.

"I can surround your child with dangerous unhealthy things and do my best to corrupt and poison them, there should be no limit to this behavior whatsoever because if I succeed it's your fault for being bad parents! All you have to do is say no, it's not like it's my full time job to make end-runs around you with the aid of behavioral science and psychology and a budget, no no no guiding your children morally is as simple as saying no once, are you too stupid and lazy to do that?".
