Over the last couple months I was beginning to loose faith in Gruber's ability to present a good solid argument. In one of his more recent posts Gruber does an excellent job at addressing key issues concerning the open letter from Steve Jobs about removing DRM from music: http://daringfireball.net/2007/02/command_option_control.
He does a better job than I could have at getting at the crux of the matter. I still really wish he would do away with calling people jackasses. You hear me John, you are a better writer than that and can do a much better job by convincing people with solid research and well composed arguments.
It's well worth the read.
