Personally, I think it's a shame. GPL generally puts me off as the licence is too complex for me to understand and I don't understand in what situations I can and cannot use it. MIT, BSD etc are simple enough that even without a legal brain I can get the gist of what I can and cannot do.
On the other hand we are open regarding Plug-Ins.
I hope this makes sense? At the end we are not specialist on the legal end of things.
