If I say something you disagree with... I'm not violating a "Non-Aggression Principle" - unless you think that opinions make you weak (I believe diverse thought makes you stronger - can't get new ideas without communication).
And if you think communication REALLY is "aggression"... how do you pair the fact that you "forcing" your opinion on me about my opinion on advertising goes against your own principle? Isn't it kinda... a hypocritical blackhole of an opinion?
Sharing info isn't itself immoral... it's LITERALLY the bedrock of civilization, free will, free speech, self defense, etc - all start with communication. The right to say stuff others don't like or even GASP saying stuff that make them uncomfortable - like pointing out your paradoxical opinion. (HOW you share CAN be immoral... but not sharing/communication itself)
Advertising, at it's core, is sharing information. Without freedom to communicate? without the ability to share ideas? We'd be afraid of fire. we would be monkeys in caves...
