WPTavern has posted an interesting discussion in the form of a chat transcript pertaining to the issues surrounding GPL(and Non-GPL) licensing of WordPress themes. If you are a theme creator, or just have an interest in the legal aspects of GPL licensing of WordPress themes, I’d recommend checking it out.
It’s a fairly informal discussion between Ryan Hellyer (of PixelPoint.com) and an unnamed “specialist in copyright law”. And while Ryan freely admits to not knowing whether what this “specialist” says is true or not, the discussion is pretty interesting.
They get into some details that often seem to be overlooked when discussing GPL licensing, such as having a copyright to the design of a theme separate from the backend code, and beach of contract issues. Law geeks will probably get the most of out it, but it’s not too full of legalese, so most people should be able to follow it if they are interested to learn more about the subject.
Take it all with a grain of salt though, since the “specialist” is unnamed, and his opinion is just that, HIS opinion.
That said, what are YOUR thoughts on the matter of GPL and Non-GPL licensed themes?
