I don't think that
toma's point was that the encrypted
software is copyrighted by AS, but that any complete program
to
decode software encrypted by them would be in
violation of their copyright, since it would by definition
include the copyright phrase (or something that eventually
evaluates structurally to that phrase, no matter how obfu'd).
By the way, even a program like
print "foobar\n";
ends up being a program of about 500kB when it is made into
an executable by AS's software, IIRC.
