I tend to agree that people who write software should -- where possible -- licence it so that people using it for commercial purposes either need to release the source code (GPL) or in terms similar to Fred's ImageMagick scripts.

The reason for this is that there is a very active competition between OSS (open source software) and non-free software and if OSS can access libraries which non-free software cannot, it gives OSS a very much needed advantage.

That being said, these scripts look incredible! We shouldn't focus so much on the licence but rather in the incredible effort the author has put in, and the knowledge he displays (I think it's pretty impressive!)
