The problem isn't The Guardian or The Daily Mail, it's that people read them and use them to prop up their very narrow worldviews. Either group could trivially shift their paper of choice to the other (or one of the more moderate alternatives) -- it's not an issue of availablity. While The Guardian isn't for profit, they still rely on the market to provide money for them, either through buying the paper or donating to the trust. The fact that the BBC which can (and sometimes does) shut it self away from any money raising concerns is more centric than the Guardian suggests that the ownership model doesn't inform the editorial much.
