How do chip manufacturers accomplish to keep the pieces of software that runs their hardware secret?
This assumes something we don't know to be true. The private key for Intel's backdoor "Management Engine", for instance, might be shared among some people. Just because that key isn't common knowledge doesn't mean it's an effectively well-kept secret either. Absent clear indication to the contrary (such as: a leaked key confirmed to be the correct key, a copy of a document from Intel or one of Intel's partners indicating the author has a copy of the key) I'd probably consider what anyone claims to be speculation.
