Open-source is largely a trust network. I don't mind if someone is an arrogant SOB, intolerant of n00b questions, or has an ugly website... IF I can trust their word about the code they produce, AND if they are still able to maintain an active community. There are implications about the long-term ecosystem regarding the particular project in question if the leadership falters too frequently or too severely, and the support network (community, business, labor, mindshare, et cetera) around a project is a vital aspect in making IT decisions. If you can't trust upstream providers to be clear and honest with respect to code, the future doesn't look so bright. While the proof is in the pudding, I have neither the time nor the inclination to thoroughly vet every change or release (this gets back to Open Source being a trust network.)

The blog post comment that you refer to seems to reflect a poor thought process. However, mine has a little more reasoning behind it.
