What do you think or make of this idea about advertising? Do you agree/disagree? Why?

I think 

that "Bill Cosby" was right,

 because the purpose of advertising is to give people information about some product, not to force them to consume or use that product. I agree to the proposed because I think that advertisments have to be used the right way, just to expose a product and to expose a brand, not to despise others brands.
