Without a doubt you could give some great insights and a lot of useful information. But to answer your question; No, you alone could not write an objective encyclopedia article on the subject.
Ok, so if a bunch of folks write about a given scientist - 2 being friends of the subject, the rest not - then by this logic the resultant copy they create as a collective should be objective. Great, problem solved.
Where did I suggest they shouldn't be writing about it? All I said was alone a single source with a biased outlook can't offer an objective view.
"Citizendium hadn't fell apart"? Hyperbole in the extreme.
