The whole point of the GPL is that you can't stop redistribution no matter what you sell it for. I can pay $100,000 for a single CD and if everything is GPL I can put that CD's contents up on the net freely the same day I receive it, free to anyone to download. The QPL has that same restriction. > > > in this case i think the QPL discriminate against people wanting to write > > > commercial software with Qt. > > > > The GPL does too, and in the same way. > > You just say you can sell GPLed software, so the GPL don't make this > discrimination. Yes, but the cost is not for the code, but rather for what you're putting it on.

You can sell it. Realize that when you buy a Debian CD it was sold to you. You're only paying for the media of course, but the GPL software was sold to you on that media. You payed to have the stuff distributed to you, not to have the right to have the code. And you can't under the GPL or QPL take away the ability for someone else to distribute the results as far and wide as possible should they choose to do it. -- Show me the code or get out of my way.
