That's right. However these are AFAIK the only versions under the GPL
without restrictions.  The widely used 2.6* versions are under a non

distribute only parts of it.

In fact there used to be a long discussion whether to keep the
for-your-eyes-only feature in OpenPGP or to drop it.  It does not
belong into the standard as OpenPGP defines a message format and not
an application.
