But the people with those skills (the system designers and neer-peer nation-state intel/military) would probably not have an incentive to do it.
Just not true. If you have time take a nice course in computer science, many are online, or teach yourself programming. "Absolutely anything" is not possible in software, and your views of the ultra-elite cabal are straight out of the movies.

Even with a lot of time and direct access it may be impossible in many circumstances. Something as simple as my G1000 firmware update now has to be signed with Garmin's private key, similar to the Apple-FBI issue. The ways around this rely on discovery of errors in the code (which is what the FBI may now be paying outsiders to do.) I agree with your assessment.
