We have had open source wireless drivers long before BCM did any thing to "ease" the so called complicated safeguards to prevent rogue use of the wireless devices. I think secret sauce has been the case for many manufactures. NVIDIA, for example, will not release their graphics driver. And how dangerous can that be, as far as safety is concerned? Has nothing to do with safety or modification of driver source to do harm. It has much more to do with protecting proprietary functional design secrets. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
