Gave away?

Tom says " work they gladly gave away in the first place."

The law case is brought by the authors of Busybox, the guys who own the copyright; their lawyers are the 'Freedom Software Law Centre". That they released it under GPL doens't mean they gave anything away; merely made it availabe to others free of charge IF they adhered to their conditions.

BTW Mountford D. if it's based on Busybox there isn't any 'proprietary added stuff' - the GPL says the GPL applies to the new code, any changes Monsoon are required to make public the source of any changes they make.
