You're very confused. Part of the confusion surrounds the difference
between Open Source Software and Copyleft. Also, your viewpoint is
strangely skewed if you can draw a parallel between:
* a commercial restriction requiring payment for /any/ practice of an
invention, including a completely independent implementation, and
* the requirement to share with the community at large the results of
modifying a program which is already offered, in a spirit of
sharing, to that community.
The former is obvious capitalism; the latter an attempt to promote
sharing in an arena where there is far too little.

Ages. We have good crypto programs already, thanks. Have a `?'.

This is a very garbled account. The `original' PGP program /was/ free.
Here's a quote from the PGP 2.6.2 documentation:
: PGP is not shareware, it's freeware. Published as a community
: service. Giving PGP away for free will encourage far more people to
: use it, which will have a greater social impact. Feel free to
: disseminate the complete unmodified PGP release package as widely as
: possible, but be careful not to violate U.S. export controls if you
: live in the USA. Give it to all your friends. If you have access to
: any electronic Bulletin Board Systems, please upload the complete PGP
: executable object release package to as many BBS's as possible.
: You may also disseminate the source code release package. PGP's
: source code is published to assist public scrutiny of PGP to show that
: it has no hidden weaknesses or back doors, and to help people to find
: bugs and report them. Recompile it and port it to new target
: machines. Experiment with the code and learn from it.
(It then goes on to say that it should't be used for commercial purposes
in the US and Canada, but that was because of the RSA patent issue, and
not any commercial designs of PRZ at the time.) Earlier versions were
released under the terms of the GNU General Public License (GPL) , and
were therefore Free Software in a very strong sense of the term.
PGP Inc /later/ formed and decided to turn PGP into a proprietary
program. I'm told they did a rather good job. They added many more
algorithms and features, certainly, and some of them at least looked
like good ideas.
As I understand it, the competition to this version /didn't/ come from
the old PGP 2.* build, which was largely incompatible, but from projects
such as GnuPG -- the GNU Privacy Guard -- which is a complete ground-up
implementation of the public OpenPGP standard containing no PGP code at
all, and released under the GPL.
In fact, I suspect that PGP Inc really foundered because of internal
political wrangling over source code availability and PRZ leaving, the
latter causing a loss of faith in the security of the program. So, in a
way, they failed because they /didn't/ release their sources.
