Selling Drupal modules under a non-GPL licence

Selling Drupal modules under a non-GPL licence

I'm not a lawyer (I'm a CTO), but I feel something is not O.K. here:

They are selling Drupal modules for money -  what is permitted by Drupal's GNU GENERAL PUBLIC LICENSE Version 2 - but also they are restricting alterations and copying. As I know all Drupal modules inherit the GPL licence from Drupal.


I think they basically break this with their software licence agreement what you have to accept while purchasing a module from them. 


Here are the 2 most important parts of their licence agreement:

"5.2 No Alterations

You may not modify, adapt, translate or create derivative works based upon the Software."

"5.4 Transfer

You may not rent, lease, sublicense, assign or transfer your rights in the Software, or authorise all or any portion of the Software to be copied onto the computer of another user or another legal entity, except in expressly authorised cases."


Is this legal?

What if someone buys a module from sellxed and uploads it to as a contrib module? ;-)

AnimGif and ImageCache plays well with Image Magick

The good old animated Gif is a cool format again. It works on everything, no Flash or HTML5 video needed. You can handle it as simple as a static image... or not? By default the majority of Drupal installs are using GD to create thumbnails (image styles). But the stock PHP GD extension  (coming with mod_php) lacks the functionality of properly handling animGifs and your mainpage or lister pages will remain static and boring.
