fault?
ref: "The discovery exposes the dark side to a free and open source software movement"
You're kidding, right?
I hope like fuck the author was being sarcastic or otherwise trying to be humorous, because if not he comes off as quite the shill for the proprietary crowd. I hate to be the one to inform the author of this, but proprietary packages are also prone to being used without the guidance of those most knowledgeable. Usually because the budget was spent on the package, not on the necessary training or support. Perhaps if the author had any real world experience in the field, or perhaps bothered to do his research, he would have discovered this. Or perhaps he does and he did, in which case there's really no excuse for such a statement.
Instead of blaming open source, I suggest the author directing future fault finding statements at the real cause of the problem: management that refuses to allow those implementing solutions the time or funds to get properly trained in the technologies they are using, be they proprietary or open source.
If the statement was, in fact, meant to be humorous, please excuse my critical humour failure. After 6 days spent fixing the fuckups of some untrained scapegoat who was using an expensive proprietary package, all because his management refused to spend 1% of the package cost (and about 10% of my fee) on appropriate training, such inaccurate and outright slanderous statements really get my dander up.
