WordPress themes has to be licensed under GPL

Direct from Heist online… or actually within the wordpress news as well
A reason not to use wordpress for commercial projects.
Yes.. the artwork does not need to be GPLed, but all your HTML layouts along with custom PHP stuff will need to be GPLed.
I’m sure a lot of people have broken this license already, but hey… when it comes down to it. You’re still in breach.
oh actually: just read you can license your CSS under othe license… well I guess at least your layout should be safe then. But not your PHP codes =]
So now I can ask some big names who uses wordpress to give me their themes?
