Sigh - no, that's _not_ what the GPL says. if you've ever looked at it
at all you'd know that it explicitly _allows_ sale of any GPLed software
for whatever you can get for it.. but you have to give your customers
the source code as well! Including any improvements/changes you've made.
And your customers are free to go ahead and sell copies of whatever
you've sold them. The original comment about commercial product perhaps
refers to Cygnus Software, who sell GCC and offer support to their customers.
Essentially, they sell support. They've also contributed many improvements
to GCC back to the free software community.
