Am I down on Open Source?

Following yesterdays post on the three biggest lies in open source I received a couple of emails asking whether I was grumpy when I wrote that article or was I getting down on open source.  Though yes I may have been grumpy (not unusual for me in the morning), I don't think that affected my article.  On the other hand, nothing could be further from the truth than saying I am down on open source.  I just call them as I see them.  I continue to think open source as a model is great way to get a software program into a tremendous amount of people's hands.  It is an efficient distribution model when done correctly.  It has proven that you can turn out enterprise class, quality software that competes favorably with the very best that commercial software vendors can develop.  But I try not to be so zealous in anything that I can't see the trees for the forest.  Open source has its cons as well.  I merely pointed out 3 that I have seen in my dealings.
