At the very least they could start selling some DD-WRT routers to appease the critics and make them forget all of their other products are closed, but they aren't even willing to do that.
This is why I always buy Buffalo routers. They are marginally more expensive, but in the same way I will intentionally buy laptops that ship with Linux as a price premium, I'll also buy routers that ship open source firmware by default because my money sends a message.
It does not matter that I replaced Ubuntu on my Galago with Arch or the DDWRT on my wzr-n600 with OpenWRT, becauase I'm on the books at these companies buying hardware running open source software.
