Which is funny because the only thing really that I see people say that because is the fact that you can't remove freedoms from the program then pass it onto users.
The GPL keeps software free forever. It's more free overall.
The likes of BSD are pushover licenses. They'll let you strip the freedom from them, but that results in the end users getting less or no freedom.
On topic of the original post, I actually make an effort to use more GNU software. I love it, I love the software, I love the philosophy. I want more of that.
