Writer who writes not out from his own mind but out from another person's

Sometimes I am wondering. I am wondering whether all writers write and share their views. That is their own views and not other people's view. Of course I am not talking about reporters. Reporters report on events, incidences and quote on politicans' saying. I am talking about journalists, analysts and commentators. The articles published in the newspapers do not seem to carry the views of the writers but of others. They seem to be the soldiers who carry out orders from their superiors. They are the slaves who pen for their masters. Their articles carry the comments and arguements that are skewed, biased and prejudiced. Hardly convicing.
