The >=50% he was wrong about (I phrased it carefully, it could even be 99/1, as he has been Quite Seriously Wrong about many other things (how to lead FSF, how to communicate with the public, how to behave at conferences)) is likely of vastly greater importance than the few minor technical aspects he was right about.
I'm on Team Free Software but I'm also on Team Productivity and it turns out that software engineering matters a lot to the latter and the quality and quantity of engineering effort put into free software is a tiny, tiny fraction of that put in to nonfree software.
I doubt the right way to change this is by yelling at/chastising users and developers. If it were, Stallman would have been successful. As it appears, he's been mostly a failure.
