I'm free to choose whether or not I do business with a corporation selling sugary drinks which I already know to be bad for me, whose power to modify my behavior rests on its ability to convince they can improve my enjoyment of life. I'm much less free to choose whether I comply with the government, whose power to modify behavior is ultimately derived from the threat of men with guns coming to lock me in a concrete cell. Advertising is memetic pollution but I'll still take it any day, every time over government compulsion; the equivocation of the two is ludicrous.
