As far as I know, too many entries in wikipedia are rated  as Start-Class (see e.g.  the entries on Michael Albert, Murray Bookchin and lots of others) but I've never seen 
such massive editing. Usually, for copy editing to be done in good faith and not as an excuse to interfere with the content, it should be done on a piecemeal basis, a sentence at a time, so that objective readers can assess it. The fact that nobody can assess Spylab's massive editing, unless one is prepared to spend as many hours of work as the ones he spent on this, easily creates a suspicion that his motives are far from innocent.
