No.  By using IDEA you show that there is still an interest in
patented algorithms.

It says somewhere:  If you want to make money with PGP you have
to arrange with me how I can get my share.  This does not qualify it
as Free Software according to any definition - except for those of Apple
an MS ;-)

It is really easy to fake the keyID, the same key is used or signing
and encryption and you can tamper with an encrypted text.  The last
point is only fixed in the OpenPGP update which is implemented in
GnuPG and PGP 6.5.8 (MDC on encrypted packets).
