If, by "self-appointed authority
, you mean the certifying entities within the FAA, then their standards for 
avionics performance have racked up a pretty impressive record for safe 
operation. 
If, on the other hand, by "self-appointed authorities", you mean any one of 
the numerous such entities within the experimental aviation community, you're 
right: I wouldn't trust them either.

<<<...The wiring problem may be as simple as adding RF chokes 
(little iron donuts) to the device's power lines...>>>

I guess the PhD's who developed SFS
 are really lamenting the fact that they didn't have your BSEE available to 
them. I'll bet choke cores are much cheaper than the ASIC's, shielding, and 
other technology they used to refine the RF immunity embodied therein.
