|Did you read the license?|
The majority of the software in Debian is licensed under the GPL, that is why Debian is referred to as licensed under the GNU GPL.
I would think the license would be applied to the act of final distribution of Debian, to the source LiveCD, or other ways. So that when one receives the operating system they have to follow the same terminology in modifications.
The license aims to ensure the that operating systems be called "GNU/Linux" in any derivative works, like Ubuntu. It also aims to ensure that any software licensed under it has to be call "Free Software." But, one could use the license to ensure that the OS be call "Linux" and the software be called "Open Source." That is my paraphrased summary of the ACT License.
I didn't write the license so I don't fully understand myself. The only information I have is the link to the license at inatux.com that I already posted.
