Advertising is not objectionable per-se, but disrespectful, manipulative, uninformative or boring ads cause consumer to think negatively about the advertiser. Print media advertising is extremely easy to skip - even a double page ad takes only a second or two of the reader's time. By avoiding commercial radio. Only blind people and the house-bound escape these. Advertising is part of life.
People expect to hear about phone company products and prices through general advertising.
Can be extremely informative. Text, graphics, pictures, forms etc. A large amount of information can be put in consumer's letterboxes or mass circulation printed publications. Can't give price lists, or any complex concepts. Like TV except much weaker because of lack of images.
