This is what you appear to not understand -- you /can/ in fact sell GPL software. You can even sell other peoples' GPL software. There's nothing wrong with it at all. All the Linux distributions you mention like RedHat and OpenSuSe contain the Linux kernel at least which is GPL'd and they sell it quite easily with no complaints from anyone because its legal.

Of course, on top of this is the issue of dual-licensing. Any code you own the Copyright to you have every right to sell someone under a different license as well as distributing it under the GPL (which MySQL AB does with the MySQL server software).

You really need to understand the GPL better.
