The Free Software Foundation considers the BSD licenses free.

The ORIGINAL BSD LICENSE with advertising clause is free, but not GPL compatible:

I hope this clarifies things.

The FSF's concerns are that since the permissive licenses are not copyleft, there's no guarantee that they will remain free. Companies like to take permissively licensed code and make nonfree forks all the time. It's what went on with OS X. The FSF's position is that they aren't in the business of giving handouts to companies that want to take what they can and give nothing back. They have never said that permissive licenses are not free. If you can cite where they have, please link to that. :)
