Re: Hope they win.
Thing with what they claim burdens their electricity, that is a stretch since the router is already there using power for your home wifi anyway, the open doesn't incur anymore power then if its off.
I'm no expert in the matter, but I would imagine a router broadcasting and receiving wireless signals at a strength required to penetrate walls and provide a reliable connection to someone outside your home would draw more power than one not doing this. What with the inverse-square law and all that, I would be very surprised if it didn't work in the same way as your mobile phone does, which broadcasts a stronger signal when the mast signal is weaker.
Also, I don't see how anyone could argue that it doesn't degrade the bandwidth. Given that bandwidth is finite (lets call it a), and some of it is being used (lets call that b), a - b < a if b > 0.
