Im not misunderstanding at all, but do you really think governments make multi-billion dollar purchaces without having technical experts go over things with a fine tooth comb. Again if only one customer nation, of which there are dozens, found something like this or if it was ever used, it would wipe out the entire export market for US high tech weapons, why would they do that when they have effective soft power ways of achiving the same thing?

Do you honestly think that all the countries buying these planes havent inspected them? Even if they were incredibly well disguised the chance of them being discovered would essentially stop the US from selling military hardware abroad again as it would be hard proof that they couldnt be trusted.

There is no reason to do that when, as others have pointed out, they can just restrict access to parts, updates and mission planning software.
