GRSecurity violates both the Linux kernel's copyright and the GCC
copyright by forbidding redistribution of the patches (in their Access
Agreement): which are non-seperable derivative works of the kernel and
(in the case of the GCC plugins) GCC. Yes: threatening consequences if a
licensee redistributes is a restraint on the "rights" given by the
original copyright owners. Those "plugins" he is talking about as-well
as the kernel patch violate the GPLv2. The GPLv2 _FORBIDS_ adding
additional clauses not-within the GPL between the derivative-licensee
and the down-the-line licensee. Bradly Spengler / OpenSourceSecurity are
violating this stipulation, blatantly, in writing. They are also
violating the "no additional restrictions" stipulation in the GPLv2.
They ARE violating the Linux and the GCC copyright.
