This is just my personal take, but what I think is happening is that recent advances in guided fuzzing have made C code (basically all C code) much more toxic and vulnerable than we thought. So, like, have Apple been introducing new vulnerabilities at an alarming rate recently? I doubt it. Is their entire kernel and userspace security ecosystem built on quicksand, just like everyone else's? Pretty much yup.
