And all it took was forcing one company to divulge its proprietary closed-source codebase because they screwed up and incorporated copyleft code deep into their core.
Imagine how much progress could be made if a few other companies were forced to crack open their proprietary closed-source codebases...
They were poopooing that before the OpenWRT case. I don't think there's evidence to suggest that the OpenWRT case made them less willing to use GPL (especially since use of GPL would always have implied they should open-source the firmware derived from it).
