The only light they saw was declining revenue from OEM's dropping them for lack of FOSS drivers. Dell, HP, IBM and most of the OEM now require FOSS drivers to win contracts. Without FOSS drivers Broadcom was being sidelined by Atheros and Intel at the major OEM's.
The only surprising thing is how much business they let walk out the door before complying. Take a look at OEM offerings and I bet you will be hard pressed to find Broadcom chip-sets in new Laptops/Desktops. They've lost nearly their entire market share in their insistence on not open sourcing.
