A spoonful of sugar helps the medicine go down.
I'd say it's definitely possible to be in business and at the same time have business ethics, to care about the truth. I don't think it's inherently wrong to publish honest opinions, as well as funny comic strips, along with the other news, if it helps sell papers.
The problems occur when business ethics, and the truth, honesty, get tossed out for the sake of profit and/or partisanship.
