In a recent turn of events, Envato — the company behind ThemeForest, ran a survey to figure out which direction they should take the company.
The discussion arose from issues resulting from a ThemeForest author wanting to speak at a WordCamp event, and the WordPress foundation not allowing that speaker to speak — on the basis that they were creating work based on a non-GPL compliant license.
As a result of the survey, Envato will soon be offering an optional 100% GPL license where authors can license their work directly under GPL. Note, the new optional license will effect both ThemeForest and CodeCanyon.
Here is the survey deck.
