I really think it will depend on the audience you would like to have. I personally really like it if someone is honest about being paid by someone as you need to handle the informations in a different way. Thus as a viewer, I will always assume that someone is being paid for it, but only these who are open with this will gain some trust over the time. These viewers who don't care after all are likely not good investors either as they just watch out for the next moon rise.
So what kind of viewers would you like to have? I think that's basically the question.
