Commercial theme authors who switched their business model to be completely inline with the GPL just like the WordPress software are cheering today as some of them have made the first part of a list that is now on the WordPress.org theme repository page under the heading of Commercial.
The links do not contain affiliate code and as Ptah Dunbar pointed out on Twitter, the links and images are randomly generated upon page load as to not give any individual site more credence over the other which is a great move. This page was created to reward those commercial theme authors who abide by the GPL with increased visibility/exposure. I think this will pan out well for those who make it on the list.
Check out the page to figure out how to get on the list and what the requirements are. By the way, I’m pretty happy to see that most of the themes listed were compiled in a list within this particular forum thread.
