And, since it’s a subliminal process, it’s extremely difficult to make a concious decision to not buy products you’ve seen or heard ads of.
Instead, I make a conscious decision to not buy products I remember seeing or hearing ads of. If you’re using subtle product placement to subliminally manipulate me in a way I don’t notice, good for you. If it’s obvious enough I remember you doing it then I will not buy your product unless it is already the best deal available (aka the cheapest per unit or best quality per price, excepting products I have had a bad experience with).
People who support censorship always believe the censors will always side with their preferences. They never consider what happens when people they oppose control the censors, and for them merely not having allied censors in place feels like they are being silenced (see conservative Christian types who inevitably get angry any time Christian-focused language isn’t enforced [aka War on Christmas or anyone else requesting a display when there’s a public religious display on government property]).
