For my 2c worth.

I read these ongoing discussions about whether a person should be able to charge for work they did under GPL.

As far as I'm concerned it's karma! Why should anyone who has done a sh-tload of work on something, and who would like to paid something for it, NOT be paid, because of some interpretation?

Let's say I develop a humungous application using Excel. it's free for anyone to do the same, but it was ME who did it. if someone else doesn't like it, then go make your own application, or, in this case a plugin.

Karma - what goes around comes around.

Like I say, just my 2c worth!

Cheers
