He screamed at people for using 'open source' instead of 'free software' in their questions, raved about the Amazon "Swindle" like a 12-year-old, and talked over and down to everyone. He was often accurate in the core of what he was trying to say, but his attitude was unhinged, and discouraged most people from interacting.
The 100 or so developers all left the talk in silence, mourning the loss of the hero we had imagined him to be.
To those who say we need him for GNU outreach: we absolutely don't. ANYONE would be better for the job.
I thank him for his many incredible contributions to our world, and wish him a speedy recovery, but we don't need these talented assholes to represent our community.
