Cory Miller’s iThemes is now completely GPL compliant! This is great news indeed and they are the second premium theme vendor who fully support the GPL and align their business models with that of WordPress and its community. Cory is a friend of mine and in full disclosure, has been an advertiser on this blog in the past. We have had various discussions about this topic and I am very happy that they have made the switch. Everyone will be better off for it.
This change means that all themes purchased from iThemes can be installed on multiple blogs without restriction but they will continue to be supported as before. iThemes will continue to sell their themes and packages and provide the support for their themes but their themes will now be licensed under the GPL. This will mean more freedom for developers working with iThemes products (and thus more sales), will lead to better and quicker resolution of issues (lesser support costs) and will encourage development and improvement of iThemes products across the board (better products for the end user and for the WordPress community). I did not want this news to be lost in the excitement of the WordPress 2.8 release and wanted to congratulate Cory on his decision.
Cory and iThemes, welcome to the family!
