You mean <i>software</i> freedom, I guess. <i>Personal</i> freedom is greater with BSD than GPL, and with public-domain software than with any of them. Personal freedom includes the right to sell software at $0.20 or $200, and the customer's right to buy it or not. For the record, I'm against software patents, but also against being forced to publish one's code, which incidentally maximizes personal freedom.
