    Oh sorry I didn't realise I was downloading the 3D driver userspace
    via firefox, or it was shipping in a ROM on my board,
    or was running on a separate processor, and certain companies were
    rather more worried about just adhering strictly to the legal GPL than
    the reasons Linus picked the GPL in the first place.

    I will give that one area is less black and white, ARM GPU companies
    have no markets outside of Linux, the whole derived from a previous
    Windows driver is a lot more grey than it is if you are nvidia.
