Abstract:

There's only one thing you can generalize: open source is a specific kind of license. And discussions about which license is better are rather academic. What you'd want to decide on is what your software should do, if and how you want to customize it, and how easy it is to get support when you need it. That means doing your homework, and finding out the real story: you'll certainly want to know what's behind the facade. And that's something that applies to software under any license.
