I'm also fearful of this setting a precedent for other vendors. I'll highlight, as it was discussed in our last Linux wireless summit, with the way things are going forward for all companies with 802.11 doing Single Chip designs combining more and more technologies together (first it was Bluetooth) and moving move towards a big fat firmware model (worst case Ethernet like 802.11 drivers) the blending will push a fine line even further as technologies used to the archaic patent licensing model get combined with technologies that were free of this crazy ludicrous archaic business model practice. Apart from firmware architecture in consideration for the technology combinations this also has implications for open firmware. The division of where companies are willing to push out open firmware is on the line here. I'm not only concerned with the removal of open firmware as an option but also seriously concerned over the quality and *security* of such firmware, just as I've always been with the quality and security of proprietary drivers. In the good 'ol Atheros days were able to innovate with the community on open firmware first with ar9170 which lead to carl9170.fw, that proved as great proof of concept to open firmware further up, even with the support of Tensilca on ath9k_htc, albeit under the Clear BSD License which also explicitly removes any patent grants. The upstream linux-firmware for ath9k_htc however is under the old Atheros firmware license which does provide a limited patent grant. The line was drawn on ath10k...
