It's impossible for one news source to be unbiased, and the delusion that it is unbiased is dangerous. If you truly believe a source is "the truth" and unbiased it allows you to switch off any critical thinking; the information bypasses any protections you have.
Much better to have many news sources where the bias is evident and the individual has to synthesise an opinion themselves (not claiming this is perfect by any means, but a perfect system does not exist).
It is obviously the case that Wikipedia is biased, and I think competition is a great thing. We would be better served by a market of options to use our own faculties than a false sense of comfort in a fake truth.
