    Yes, but in highlighting the possibility of evil intentions you
    distort the fact that usually there are no such evil intentions...

    I think that's a possibility. I don't see how it's functionally
    different from the usual case where the manufacturer can't modify the
    device without the user's consent simply because the user has physical
    access to the device and the manufacturer doesn't.

    Users benefit from the ability to get software updates, from the
    manufacturer, to resolve problems, fix security vulnerabilities, and
    provide updated functionality.

    You're harping on the "cannot legally", which is fine but irrelevant.
    Whether it's a legal requirement or a business decision, the result is
    the same - neither forcing the manufacturer to make the device
    non-updatable nor forcing the manufacturer to use different software
    benefits anyone. I don't know of interesting cases where the
    manufacturer makes the device non-modifiable out of sheer
    bloody-mindedness.

    I don't believe that the existence of this clause will lead to more
    manufacturers making their devices modifiable - there are too many
    other options if they think that non-modifiability is important to
    them.

    [Note that I *do* think it's perfectly appropriate that authors who
    feel that they don't want their work used in such devices should be
    able to license them in line with that belief. I just don't think it
    has any practical value aside from making them feel better.]
