Not a fan at all of Gruber. But more importantly, Stallman's lack of hygiene is not terribly relevant to his points. We're not talking about being friends with Stallman, after all.

I also think when RMS made his more salient and prescient points, most people weren't familiar with him personally, just with his remarks. The world was less connected back then. So his personality flaws really didn't make a huge impact (nor should they have).
