Uh, you can trivially write a program that "debugs" the frontend using the
other program only via commandline for example.
Also it would be rather annoying if no closed-source program was allowed to
use grep, sed or even the shell itself, wouldn't it?
But mostly it is a clarification of copyright law, and what is considered
a derived work and what isn't, so if you have an issue with it my first suggestion
would be to complain about your politicians having written an absolutely sh*tty
copyright law that leaves everyone guessing what it actually means.
