No one is required to buy GPL'd software from Red Hat (and, in fact, they don't offer any for sale). The software itself isn't sold, value added services are what's being sold. So no, GPL software is not being sold commercially by Red Hat. > What MySQL AB did was: > > If you want to make a *Proprietary* application, then you have to > buy a special license. Yes, they're *requiring* people to make a cash outlay for a license when they've not been doing so in the past. That's making it "less friendly to commercial developers." > This change resulted that you _CAN'T_ make proprietary softwar > derived from GPL'ed Libraries. Again, making the license "less friendly" (and sabotaging, in the process, RMS's goal of keeping the GPL "viral.") It's also disingenuous to "sell" a commercial license covering the same source code that you also offer under a GPL license. > HOWEVER, of course you can sell (commercial distribution) GPL'ed > software. Yes, you can. But no one is required to pay for it. MySQL is requiring people to pay a license fee for software that under any other circumstance is Free (GPL). > The license one program is distributed with has nothing to do with > its commercial exploration. The licese a program is distributed under does influence the decision making of those that use the software (or in this case, develop applications that make use of the software). > MySQL AB basically said nobody can use MySQL libraries for non-Free > Software. Again, defeating the purpose of the GPL.

I'm begging to think these "dual license" schemes are more bait and switch screw job than a legitimate attempt at producing commercial software and allowing it to be used for "Free" only under certain limited circumstances. At any rate, what "absurd assumptions" were made in the text you quoted? -- Chris "Build a man a fire and he will be warm for the rest of the night.
