In case of open source licenses, the opposite of "restrictive" is "permissive", not "more free". Yes, the BSD license has fewer restrictions than the GPL. That makes the BSD license a more permissive license, not necessarily a more free license. The BSD license allows licensed code to be used in proprietary software but the GPL requires any derivative work to be licensed under the GPL thereby guaranteeing that the licensed code is always used in free software. Therefore, one can argue that the GPL license is "more free".
