Forbes is running an article titled Linux's Hit Men. Initially I had a hard time telling if the author was being serious or sarcastic. Based on his previous writing I guess he is serious. I'm sure big companies like Cisco and Microsoft is very afraid of a foundation [that] has $750,000 in the bank and one lawyer who works for free, part time, when he's not teaching classes at Columbia University

The rules of GPLed software are simple. If you don't want to follow them then don't use the code. Personally, I prefer licensing my code under more liberal terms like the MIT license. If people want to take my code and make millions, good for them. Other people don't want that and use the GPL. RMS uses the GPL to try to encourage people to make source code available.
Linksys knew or should have known what they were getting into. I have no pity for them.
