As can be seen from the Update to that linked article, I think a big part of the problem is that these Web 2.0 "journalists" don't read, so in a game of telephone it's been turned into "FSF head Richard Stallman issues press release saying Jobs sux". If we're going to do that, you could manufacture about 300 scandals from his blog; "FSF head Richard Stallman equates U.S. President to Saddam Hussein!", etc.
Maybe it's still contemptible as it stands, but I think people are either missing or deliberately ignoring the context when evaluating it. I take his "politics" ticker as closer to an IRC chat than a place for carefully thought out statements (that's what his Essays are for). I like that in geek culture we don't have this weird demand for people to be 24/7 ensconced in a professional PR-oriented persona, like a CEO or politician, but allow people like RMS, ESR, and Theo de Raadt to have crazy personal opinions. (Heck, Jobs had some pretty offensive and harmful opinions about science and alternative medicine, and we allowed that.)
Honestly I'm more offended by this level of shameless profiteering with Steve-Jobs-death linkbait. Huffington Post, for example, shat out 188 separate Steve-Jobs-death posts within 24 hours: http://exploreto.tumblr.com/post/11114571981/huffingtonpost-...
