It shows very well where GrapheneOS shines and also, what exactly other OS's maby lack. But it gives a lot of nuance and opportunity for any user to decide for him or herself, if a threatlevel applies to them. Probably less than one percent of our population is fearing the threat of someone stealing their phone and hacking it physically (as many people use no pin or a very weak one).
