Gentoo does not distribute gnupg or IDEA.
Gentoo provides the instructions of how to build these components from source.
Gentoo is not distribution in the usual sense, but meta-distribution...
If one distribute a pre-built packages he set the bindist USE flag,
and IDEA is disabled.
As far as people checked (for this and other packages) this is valid
and confirms to GPL.

There are people with IDEA keys, they would like to continue using these keys.
As long as they are leagalley entitled to, I don't see why this should
not be allowed.

The information is correct. Whoever want to use IDEA should be exposed
to this information.
However... I cannot access this URL anymore.
