Changing from closed source programs to open source programs is a hard thing to do. Many people will resist that change fiercely and will pull every trick out of the book to justify their objections to that change.

Sometimes they have no choice and when a company is instructed to move from a closed source program to an open source program it is inevitable that, as the old Chinese curse goes, there will be interesting times.

For this change to happen there are several courses of action which can be taken. As a metaphor think about removing a bandaid. There are three ways you can remove a bandaid. The first way you can just count to three and just rip it off when you reach two. Sure there will be a bit of pain, some screaming and a few choice words but the bandaid will be off and the pain will subside quickly.
