Oh sure, definitely, that seems like that is within the scope of the currently claimed power. As far as I know though the operator has the option of closing up shop however and therefore is not being forced to work against their will, but not a fun choice though.

I am interested in any case law that disallows the operator the option of shutting down rather then implement a back door or anything similar.
