I was seeing few YouTube videos in which people where demonstrating the installation procedure for modified Raspbian image on orange pi pc. I could also see the icons of pre-installed Mathematica on them (although I couldn't see them open it).
Now, from what I know Raspbian has a few licensed software packages such as Minecraft and Mathematica which are only allowed to run on a Raspberry Pi for non-commercial usage (which is the reason why Raspbian for PC and Mac doesn't have them). I wonder why usage of Raspbian and hence Mathematica on non-licensed devices is not questioned by anyone.
Is this legal? Or am I missing some agreements? I have an Orange Pi and would like to clear things up before I use Raspbian (although 2 years old and not updated) and hence Mathematica that comes pre-installed in it.
