OK, the only ideal owners of a newspaper would be anthropologists from another planet who cared nothing about Earth affairs and only documented what they saw. But even failing that, you seem to see better journalism from competing groups of intellectually honest yet openly biased sources than from supposedly unbiased sources. With biased sources, you can just read every side and form your own opinion. With supposedly unbiased sources, you'd have to do the same thing anyway but it's much harder to figure out what their biases were to begin with.

And sure, people can be intellectually lazy and only read sources that they agree with, but the fallacy of unbiased journalism is that a handful of media outlets will end up providing that anyway, just with the illusion of impartiality.
