Well, code under both the MIT and BSD licenses can be used in GPL's code, but since licenses like some of the BSD licenses allow for future code to be closed, there for removing the freedom of future uses, the GPL code can't be used in the BSD projects. Which is why GPL projects tend to do better (Example: Open Office [Apache] vs Libre Office [LGPLv3]). The GPL code can use all the features of the BSD code, but not the other way around. "GPL is not freedom". You definition of "Freedom" is different then mine. Your version of freedom is giving people the right to take away other people's rights by locking down code. That's like saying one country is "more free" because they don't restrict people from owning slaves. You might as well just put your code in the public domain at that point.
