If I understood GPL right, GPL allows to modify the code of a GPL licensed product/code and rebrand it to fit on one's need. Only the restriction is to keep the original copyright information intact in the codebase. If Daarkoob CMS developer decides to distribute the code and also IFF it is based on Elxis which is distributed as GPL software, than Daarkoob CMS also has to be redistributed as GPL licensed package (Only applies if the author decides to release to the general public). This is the freedom in Open Source World!
