> Do you also distrust those?
I suspect the OP made a mistake and forgot the word “not” in “I'm accusing Apple of lying, but I'd like to get more context than” (otherwise the “but” makes little sense).
I expect they are asking in good faith if there are audits, not accusing the auditors of being corrupt.
It really comes down to whether we trust Apple to do the work; auditors can be found that will certify anything you need even if not at the fraud levels of Arthur Anderson.
And this kind of thing can be hard to independently verify.
Given Apple’s track record I suspect they actually do care about this internally and spend the effort to make sure it is “real”.
