The Wikimedia Foundation control Wikipedia, the subbordination is done by them. Editors are only as free as they permit - the two are inseparable, to suppose otherwise is as supposing chromium is independent from Google.
Of-course Wikipedia is a useful tool, so what? Are they exempt from criticism?
What is it you are saying? You abuse the English language; by definition a journalist is not a shill. Many mainstream shills may claim to be journalists, but that does not make them so.
Well, your definitions are eccentric. For example, Luke Harding is accredited as a senior journalist at The Guardian; he shills for the UK security services. I'm not sure whether we disagree as to what a shill is, or what a journalist is. The only journalists that I know of that are not shills are independent writers, like Jonathan Cook and Peter Hitchens.
