Linux's Hit Men (Forbes)

Forbes, a magazine known for making ill-informed hit pieces on free software. But notice nobody was forced to give up source. Cisco was given the option to rip out Linux and use another OS, which they now do in their latest WRT54G router (VX Works, which they have to pay for, but runs in a smaller footprint so the routers are cheaper to manufacture, more than making up the cost).
