This is incorrect on more points than I can conveniently enumerate.
To hit a few easy ones:

* TeX does not require file name changes.  It's just that there are
  trademarks on the symbols \TeX and TeX, and those licenses involve
  passing the gruelling TeX regression tests.

* LaTeX doesn't require file name changes either; we had a big
  discussion with the LaTeX Project about this, and they were
  ultimately very nice about making and keeping the LPPL DFSG-free.

* DFSG 4 doesn't permit licenses which require file name changes.  It
  does permit licenses which require changes in the name of the work.
  The name of the work is strictly a social entity.  A file name is
