No.  I want to say:

Knuth wanted to make TeX free, and he did.  And the LaTeX people want
a *different* license from the TeX license--indeed, they want one that
is quite possibly non-free.

Because the LaTeX people have seriously misunderstood the TeX license
in several areas, they incorrectly think their license is basically
the same as the TeX license.

Yes.  And that's the point.

But there is *nowhere* a copyright on "TeX-the-system".  There is,
rather, a copyright on various parts of it.  The conditions on copying
tex.web make no conditions whatsoever except that you copy it
unmodified, and are explicit that patches are OK.

The conditions on using the name TeX do not say anything about what
fonts you must link it with, but only that the trip test passes and
that you be happy with the installation.

Which license?  Exactly!  Can you quote it?
