He can't change the license of the original code. He can license his
own new code in any compatible way.
As a matter of practicality and courtesy, in GNU we generally recommend
that modifications to RBSD'd code also be licensed under RBSD. (Ditto
for any similar permissive free software license.)
(Including propietary ones)?.
RBSD code can be used in proprietary programs. However, it's not that
the RBSD code is being relicensed, but rather the RBSD is compatible
with essentially anything, including proprietary terms. The original
code still exists, and it is still under RBSD.
Is required I put an separator something like "The original file is
