I think this is the problem exemplified, especially the last one -- that was plain embarrassing. The FSF just cannot tactfully spread their (quite wise and forward-thinking) message. To any average Joe, the guy outside the Apple Store protesting the iPad is no different from the local drunk schizophrenic who lives on the alley corner yelling "REPENT, SINNERS!" until he passes out again.
Their concept of professionalism is flawed -- actually, a more apt predicate adjective would be "completely nonexistent." Just look at their website. 2003 wants its two-tone website design back.
