By the sound of it, Apple's offered audit doesn't include insight into the most dangerous parts of a system like this. This could easily lead to a situation where real security experts are denied access to promote influencer-adjacent Yes Men who rubberstamp the hashes matching without any question.
Hence my concern for "SSL added and removed here" - none of Google's famously backdoored infrastructure will be audited. For privacy purposes, Apple's promise is woefully incomplete.
