[wp-hackers] Plugin Licensing

[Christian Gundersson]

What Chip said is true. Check the link below for detailed information
regarding the GPL. Selling a GPL software requires only that 1. You provide
the source code to the buyers (if they want it) and 2. You can't stop them
(the buyers) from redistributing the software at will.

I'm surprised of how many "quote" the GPL but never seem to have checked
with the source...
