As an Apple customer I'm 100% happy with public developments like this. I really believe Apple tries to take hardware security seriously and an exploit it the open like this is surely to be addressed in the next generation of devices.
Apple consumer devices have been shown to resist state-level actor threats in the past and even if current devices won't be 100% resistant forever I trust Apple to be a couple of steps ahead every gen.
Of course, I'm jumping ship as soon as 100% open-source and verifiably secure HW+OS stack is available. But until then, it's Apple :P
