Looking in particular at RocketTheme. The php code in RocketTheme extensions is GPL, though the images, css and javascript are released under The RocketTheme Proprietary Use License v1.0 as quoted below. I am not an expert in law but it would seem to me from the wording that it allows redistributing as long as it is presented as is with the author clearly stated.
I fully accept that new features will only be considered as and when the budget allows and that this site is focussed on WordPress and WooCommerce. It would be nice to have though.
The RocketTheme Proprietary Use License (v1.0)
———————————————-
The RocketTheme Proprietary Use License is a GPL compatible license that pertains only to the images, cascading style sheets and JavaScript elements of RocketTheme extensions (Joomla, phpBB3, etc). produced by RocketTheme. As stated by the GPL version 2.0 license, These elements of product that are not compiled together but are sent independently of GPL code, and combined in a client’s browser, do not have to be GPL themselves. These images, cascading style sheets and JavaScript elements are copyright RocketTheme and can be used and manipulated for your own or your clients purposes.
