So far as I know, Thomas Esser, teTeX's upstream, does not have
special privileges for redistributing Knuth's .web files, nor does
Olaf Weber, the current maintainer of the Web2C distribution of
TeX, which Thomas Esser's teTeX uses as its core.
Web2C is distributed under the GPL, but the introduction to the
Web2C manual (available in /usr/share/info/web2c.info-1.gz or
/usr/share/doc/texmf/programs/web2c.pdf.gz) says the
following:
Availability: All of Web2c is freely available---"free" both in
the sense of no cost (free ice cream) and of having the source
code to modify and/or redistribute (free speech). (See section
`unixtex.ftp' in Kpathsea, for the practical details of how to
obtain Web2c.) Different parts of the Web2c distribution have
different licensing terms, however, reflecting the different
circumstances of their creation; consult each source file for
exact details. The main practical implication for
redistributors of Web2c is that the executables are covered by
the GNU Public License, and therefore anyone who gets a binary
distribution must also get the sources, as explained by the
terms of the GPL (see section `Copying' in Kpathsea). The GPL
covers the Web2c executables, including tex, because the Free
Software Foundation sponsored the initial development of the
Kpathsea library that Web2c uses. The basic source files from
Stanford, however, have their own copyright terms or are in the
public domain, and are not covered by the GPL.
I don't think that that explanation really clears anything up with
regard to redistributing or modifying TeX itself.

We've been relying on Thomas Esser to ensure that the files he's
distributing are DFSG-free, with help from us. Thomas has
repeatedly stated his commitment to getting teTeX into a
completely DFSG-free state and maintaining it as DFSG-free, and
he's doing a pretty good job.

I've actually done much of the required work as part of the
(documentation) license review I conducted a few months back.
There actually turned out to be relatively few different licenses,
and if we need to list them all in the copyright files for the
packages, we can do that. (I had actually done just that for
tetex-base, tetex-extra, and tetex-doc at one point, but pulled
the changes before checking them in. I can't recall why now, but
I suspect it had something to do with our dropping many of the
files with nonstandard licenses.)
Policy is unclear on whether merely listing the licenses is
sufficient, or whether we have to include both the licenses and a
list of every file that falls under those licenses. (My reading
is that Policy assumes that there will only be one copyright
statement/license for a package.)
