There is no hacker Cjae, this is an Adobe Developed tool to ease out the installation process for IT admins on number of computers.
Ex: You work in an organization where you have 300 computers , now will the IT admin go ahead and install the CC apps on all the machine one by one. That will be impractical and too tiring.
They will use CCP ( Creative Cloud packager) which will bundle CC application , which could be deployed on all 300 machine with SCCM, ARD and other tools (use to manager network deployment)
I have shared the links above, will suggest you read them for better understanding and usability
Having said this, the user who are connected to internet can still go to creative.adobe,com and install Adobe apps ( as in your case).
Hope this helps with a bit of understanding, but reading the CCP (Creative cloud packager) will help you know more about the stuff else feel free to contact me if you need more understanding.
Thanks,
