IIRC, one of the first public Wikipedia "scandals" involved a guy who was irate because his Wikipedia entry was wrong and he was told he wasn't allowed to edit it. Cue much hemming and hawing.

Only the "wrong" was that it included "director" among a long list of accomplishments, on account of he had directed a film. The guy's beef was that he didn't like the film and didn't want to be noted for it, and he demanded sole authority over his own historical record.

Sometimes there are good reasons to not let people edit their own articles. Sometimes there aren't. But you need some sort of coherent policy.
