I believe the only way to rethink this is this quote, from

  The LaTeX Project Public License


    The reason this requirement is acceptable for LaTeX is that LaTeX has
    a facility to allow you to map file names, to specify ``use file bar
    when file foo is requested''. With this facility, the requirement is
    merely annoying; without the facility, the same requirement would be
    a serious obstacle, and we would have to conclude it makes the
    program non-free.

Without this, even FSF and RMS would have not classified LPPL 1.2 as a
free software license. So Frank, please mention this everywhere you want
to prove LPPL is a Free Software license.

For debian people: please consider this. I believe this voids many of the
intents of the license, as previously mentioned (sysadmins can use this
remapping feature to make \documentclass{article} load some other file
instead of 'article.cls'), but this is also the reason FSF agreed that it
is a free software license.

I agree. I still believe that TeX's copyright is a trademark and a
software license combined. He could not have said: "Don't use the name TeX
if you change this file", if there was not a trade mark on the names TeX,
METAFONT, etc (I don't know the exact situation about Knuth's other
programs distributed with Debian, like Computer Modern fonts).
