It is my experience that people like to have someone to blame if things go wrong, and they feel that it's hard to blame free products (you get what you pay for, etc.). I think that this is a corollary to ``No one ever got fired for buying IBM/Microsoft''.

Of course, open source products will usually fix whatever problem you're having faster than closed source products will, and if no one is interested in fixing the problem, it's infinitely easier to fix it yourself if it's open source.

But that doesn't matter because you can't pass the buck. Which, as we all know, is the most important part of being in the IT field.
