Thesis is now under the GPL. That is, the PHP code that forms the bulk of the WordPress theme Thesis is now under the GPL, the same free software license as WordPress itself.
A week ago, I posted on the Thesis licensing controversy, closing with the wish that it wouldn’t go to court. Well, that wish was granted. I am “glad that Pearson saw fit to respect the GPL and that no blood was shed in the process” (to quote Jolie O’Dell, who has moved to Mashable from RWW).
Why should WordPress themes (not just Thesis) be GPL’d? WordPress core developer Mark Jaquith made a thorough argument that: Theme code necessarily derives from WordPress and thus must be licensed under the GPL if it is distributed. There’s lively discussion at Mark’s blog and at Reddit.
