Well, the main software components are GPLv3. But there's also hardware released as CC-BY-SA, some modules as Apache v2.0. I guess you are thinking of it as a library.. In that case you can argue that a copyleft license would restrict the possible adoptions of the system. But this is a framework composed of many modules, most of the time you will interface this system with your own stuff using agnostic protocols, so.. what would be the legal problem for a closed-sourced business to use it?
