How advertising informs to our benefit

I do not agree with the views of the writer. Mainly due to three points,he said that advertisement's information comes with no cost,to bring forth information from other sources and advertising include interest of public, which i do not agree.
Firstly,the writer states that the information given by the advertisement is free and need not pay at all. However, have you ever realized that advertisement loves instilling fears in the hearts of other, to increase "awareness" and thus buy their products as a form of calming ourselves. Thus it is not true at all that we do not pay for the information, as we paid for their products which is just an indirect form of buying their information.
Secondly,many advertisement like to include their so-called "professional consults" especially toothpaste where they like to use doctors as forms of examples who used their product, this is a form of including information from external sources where doctors are asked to use their professional knowledge to back up their product showing how famous and widely used by prominent figures of the medical industry, especially in dentistry.
Lastly, I totally disagree with the fact that the companies includes public interest. Normally when we see advertisement of medicines like slimming pills they always highlight the benefits of their medicine, but have they ever highlighted the after effects of consuming their pill? Have they really cautioned the user that these pills are not beneficial to human body due do some harmful substance that would cause body problems? All these important cautions are not stated in advertisement. Thus they normally dun put consumer interest much to their attention.
If I would create an advertisement for a tobacco company, I would definitely not state the statistics of the chances of getting lung cancer with the usage of tobacco as it will only scare the consumers away. What i would do , is to depict smoking as a very "cool" image, as only then it will attract more consumers especially from the younger generation. For tobacco companies there would not be a need for too heavy advertisement as once a person takes it, he will thus be addicted and it will not need too much or constant advertisement to captured and preserve their interest.
However, by doing so we are just compromising on our integrity and our honesty on health issue of the nation. Thus, advertisements will only show the good side of their product, but not show the cons of their products as it will not attract people but scare consumers away.
