Drupal Pinterest Clone

Themesnap has a drupal clone but their licensing seems very muddy.
The program costs 229 dollars and they have built it on Drupal a totally open license from gnu/gpl and then their code is based on the open license , totally free skeleton CSS.
Oddly enough they claim limited rights for purchasers to reuse the program on more than one personal and one business site.
This strikes us as odd because they bundle all software together and that should cover it under the gpl.
Even without covering it under the GPL, their CSS is based on skeleton free framework.
Which means anyone can easily edit the code and make their own.

Plus the design is cloddish compared to the ease of use of wordpress or other php designs in our humble opinions.
