While this is very interesting (I was aware of some of this, but not all
of it), and I appreciate the time that you took to write it up, I think
shows that indeed the original BSD license to which the DFSG was linked
was the four-clause version. (Thanks to Charles Plessey for uncovering
The version in /usr/share/common-licenses/BSD is very specifically the UCB
version, not any of the other versions, and my assumption was that that
had historically also been the case (since it wouldn't make sense to me to
move from a less specific copyright holder to a more specific one).

Certainly agreed; however, I was specifically talking about the UCB
version as seen in /usr/share/common-licenses, so I was really being
inaccurate with my original statement.

Note that I have never argued that Debian should be recommending the
four-clause BSD license as best licensing practice. It manifestly isn't.
Only that it is and has been DFSG-free since the beginning of the concept.
