...and, also, incompatible with the GPL.

Most of the Debian concerns, though, are that they want to patch the
software: their policy on security is that they will not ship a newer
version for a security issue, but rather will make the minimal patch
to their release version.

In the LaTeX case, of course, that means they are obligated to change
the name of the package in the security release, breaking the entire
world.  Boom.

(In the specific case, the trademark does require that you call your
project something else, or risk breaking the law if there was any risk
that your version and the original version might be confused.  Which
... there is. :)
