It was a debugging symbol that a Microsoft developer either negligently or heroically included in a public release... so that explains away the "nobody would be so stupid" argument. You are aware of how the Intel ME killswitch was located right? A commented xml file included with the flashing software helpfully informed anybody willing to look that a field was related to the NSA's High Assurance Platform program. This was after ten years of security researchers pointing at the fact that this was a backdoor. For whatever reason both Intel and the NSA were happy to let the public remain needlessly vulnerable all that time... But yeah, I'm just like one of those water fluoridation loons. The NSA wasn't at all hamfisted in the intentional weakening of elliptic curves and blatant RSA bribery, this isn't an obvious pattern emerging.

I'll tell you what it looks like to me:
After the debug symbol is found, Microsoft gives a seemingly very stupid explanation for it[1]: "It is a backup key. Yeah, uhhhh... during the export control review - the NSA said that we had to have a backup key, so we named it after them..." After being challenged on the plausibility of their backup scheme they refuse to provide any further explanation.
Here is the funny part: Microsoft might be technically telling the truth about it being a "backup". Consider what else was going on around this period: ridiculous export controls on key-length, the clipper chip... and finally: government managed private-key escrow[2]. At that time the export regulations did not specify a backup requirement, and yet Microsoft claims otherwise. You know who else was talking a lot about backups? The Whitehouse, in its proposal for allowing the export of key-lengths above 56-bits - so long as applicants implement "key-recovery".[3] Somehow I don't think that we share the same definition of the word "backup".
Also, ECI Sentry Raven[4], have fun with that.
