Violation of GPL?

[Gustavo Federico Bett]

Hi

I've recently visiting the Blender site, and i found an article
mentioning a website that is selling open source software (the GIMP,
Blender, OpenOffice, Audacity) at a low price, but, changing the name
of the product, and not naming the original authors.

This is not a violation of the GPL?? 

I know that you can charge for the media, but you can change the name
of the product and not be able to realize that until you actualy buyed
the CD?

this is the link to the article:

Thanks in advance
