Sometimes someone has to step up to do the dirty work and write software that can only give mediocre results. I think he's getting flack as the scapegoat for the general consumerization of Linux (ala ubuntu, gnome, etc).
Really, if people don't like these systems, or if they weren't worth the trouble, why not do something about it? They sound like itches that could be scratched. That was the spirit of a previous, less popular open source movement. Now it's full of useless bitching assholes who will spend 10x the time complaining over time actually fixing.
Note: I'm not saying that you personally are in that category. But this guy should be able to respond with "fix it, fork it, or fuck off."
