Thanks!
FWIW, this was fixed fast alright when I pointed it to the software
team that had farted this.
This happened a couple years ago.
I have seen worse than using '0x00' once: a combo of a patched insmod
to remove all the MODULE_LICENSE checks especially on "Proprietary"
AND a patched kernel adding a hook in module.[c,h] and some core net
patched code to make userspace,
"look-ma-kernelspace-gpl-will-not-apply-here" modules possible to do
network packet filtering in userspace. Which was also a nice try but
another baseless fart, beside being also terrible from a perf and
reliabiility point of view.
The squirrelly thing was that only a handful of line of code were
modified: a few needles hidden in a giant haystack.
If there were an award for "Sneakiest f*ck-the-gpl attempt", these
folks would have been winning the trophy hands down with special jury
congratulations.

In the US, in a weird twist of unintended consequences, this might be
likely a violation of the infamous DMCA.
