This new direction will deny the source code proof that allows Phil to guarantee the back door-free nature of versions through the latest 7.0.3 release. It seems such worries are a major violation of his idea on the nature of personal privacy, and I'm glad he's standing up for us all.
Fortunately, he's not leaving the scene just yet (plaintext hyperlinked by me):
While it is true that NAI holds the PGP trademark and the source
code for the NAI implementation of PGP, I'd like to point out that
PGP is defined by an IETF open standard called OpenPGP, embodied in
IETF RFC 2440, which any company may implement freely into its
products. I will be working with other companies to support
implementations of the OpenPGP standard, to turn it into a real
industry standard supported by multiple vendors. I think the
emergence of more than one strong commercial implementation of the
OpenPGP standard is necessary for the long term health of the PGP
movement, and will, incidentally, ultimately benefit NAI.
To this end, I will be assisting the makers of HushMail, Hush
Communications, to implement the OpenPGP
standard in their future products. They will be doing their own
announcement of this new relationship.
In addition, I will be assisting Veridis, a
recent spin-off of Highware, to create
other OpenPGP compliant products, including software for certificate
authorities for the OpenPGP community.
I am also launching the OpenPGP Consortium, to
facilitate interoperability of different vendors' implementations of
the OpenPGP standard, as well as to help guide future directions of
the OpenPGP standard.
