Seems to me it's a little like the pot calling the kettle black. Yes, Jobs liked his closed-platform and saw computers and other gadgets as "appliances" to sell to people in closed boxes where you can't even change the battery. But he never said he was doing anything different, and he was very successful at it. In the end, his legacy will include his personal treatment of people, the "culture" he inspired, and the commoditization of computer-related technology.
The part RMS never seemed to understand is that not everyone views software as some kind of grail to protect. I do see his point, but most people don't, and if they did, most wouldn't care. It is a conspicuously self-centered and unyielding technologist's view of the universe.
And so I think it's a little silly to see a man who has contributed little more than his opinions to the world, maligning the reputation of a much more successful man. He may not be wrong, but who cares? Just one more opinion.
