Dilbert mentions Open Source today. Or, rather, his boss mentions it "because it's free." Which it is, but it's the freedom to run, modify, and share software that's important.
In the Pointy-Haired Boss's office:
PHB: "From now on, I want you to use Open Source software for everything we do. It's free."
Dilbert: "I'll be right back."
At Alice's desk:
Dilbert: "It's an emergency. I think he's been reading."
Dilbert and Alice in the PHB's office:
Alice: "We know you have a trade publication in here. Hand it over and no one has to get hurt."
