That’s not the point though. I’m taking someone else’s code, therefore I can’t change the license because it’s *not my code*. I don’t own the copyright. If I’m copying the code from labwc, the labwc authors own the copyright, not me, therefore only they can change the license.

Therefore, if I’m choosing a project to copy to use as a base, I want to give myself the maximum amount of options for the future.
