Lacking any other indication MODULE_LICENSE is supposed to mark the license
that the code is being distributed under. If companies are intentionally
mis-using this to get around the "internal interfaces" limitations (where
some interfaces are not available unless the module is GPL'd) and the warning
message printed in the logs when the module is not GPL'd then they are
(technically) in violation of the law. (interfaces that are GPL only are
considered so internal to the kernel that using them makes your code GPL
because of the inclusion of GPL'd code. And no - I am not going to get into
that discussion - it's pointless)
In the end, using MODULE_LICENSE for any purpose other than declaring the
chosen license for the code is deceptive. So it is easily arguable that by
not including any license with the code other than the MODULE_LICENSE
statement and then trying to prosecute because MODULE_LICENSE doesn't
accurately state the license on the code is entrapment and illegal.
