Most systems that run Linux are unsupported by the vendor who refuse to provide support. This is the dividing line I find. The vendor might provide source code to the community to make their widget work with Linux but it's provided as-is and unsupported. I found this out with a dodgy NUC recently. Intel support told me that Linux is unsupported so they can't help. I had to install Windows and show the same issue before the issued the RMA.
