And this is not?

"Tired", I observe, is entirely in the eye of the beholder.

Say, rather:

"I am unwilling to compromise on this matter, or consider other avenues
of meeting our mutual goals."

Registering "LaTeX" as a trademark would have given you much more power
(i.e. real power) to discourage such things without requiring such high
standards for others wanting to play around with the code.

The second is outside of your power to prevent, as it (or its
equivalent) can be done without reference to your work, and therefore
does not fall under your legal purvey.

For example, here is a Python wrapper that makes no reference to LaTeX:

-----
#!/usr/bin/python

import sys
import os

program = sys.argv[0] + "-fake"

os.execv(program, sys.argv)
-----

Now, if my hacked LaTeX is named "latex-fake", I can symlink my program
above to "latex", and "latex foo.tex" will invoke my fake LaTeX.  You
have no recourse because you retain neither any legal right to my
program above nor any trademark rights to the name "latex".

Don't reinvent the wheel.  If you want the legal assurance of a
trademark, just go and get one.
