If I may, it seems to me that there are some serious problems with the "attitude" of the Company.
I seem not able to find ANY reference to the GNU license, not to sources, it is of course very possible that, notwithstanding the fact that it is Linux based, EVERYTHING they provide is their own independent work, but since they also provide a Linux based "Live CD", they must at least provide the sources for that part AND the GNU license.
The "general" License Agreement is here:

I have rarely seen such a restrictive EULA, between other things

Power issue with unpowered USB hubs and keyboard USB ports
Some USB devices will not work if they are plugged into unpowered USB hubs (which include USB ports in keyboards). If the hub is unpowered, all devices using it will share power. Some devices may expect or need more power from the USB port, and the shortage will cause them to malfunction.
If you have any problem with your USB devices, it is recommended that you use a powered USB hub.
I hope that quoting it on a board is not illegal...
