I'll just make an hypotesis. The origin is not very important as long as
the original author doesn't care about claiming it. Being GNU GPL (this
is clearly stated in COPYRIGHT), there is no warranty in any case. If
there is no warranty, then as long as no-one is claiming the copyright,
it shouldn't matter (for example, "orphan package").
In this specific case, there is some (possibly incomplete) authorship
information in the original "listen" package. As long as I refer to the
original package, stating clearly its origin (for example it's web
location and name), it is always possible to trace back whatever
information the original author wants to provide (in the original source
package). If such information is missing or incomplete at the origin it
is a matter of the author of that package.
Just an hypothesis or "guess".
