The comparison was intended to highlight that by giving that presentation, Matz is not simply propagandizing Ruby, he's trying to distribute accurate information. The parent of my post seemed to be critical of Matz's approach because it was humble and honest. The implication of that is either that he expects Matz and Ruby to be perfect (an impossible feat) or that he would perfer Matz to simply evangelize Ruby blindly.

I personally do not find it distasteful when someone is honest about the shortcomings of their project. It takes humility to do this, and it's totally uncool to rip on someone when they do it.
