Like many suggested, a proper fix might be harder than simply revoking a bunch of certificate like the blog authored assumed without breaking downstream features and functions in a large ecosystem and security conscious platform like macOS/iOS.
However, there is certainly a chance that Apple team didn't think the impact was that bad given all the other protections in place.
When Steve Jobs was alive, his Apple company email was leaked and published and Apple customers emailed him for features and fixes all the time and he personally responded once a while. Tim Cook did the same a couple times too. Perhaps the blog author should write in to the new CEO John Ternus or SVP of Software Engineering Craig Federighi too to see if they can fix that.
