But in reality, I think this is a scare piece meant to drive people away from using graphing OS.
You aren't born with a GrapheneOS phone and you can't trivially discard or swap your skin color. Born immutable characteristics of humans are a different moral category entirely, even if the statistical inferences are superficially similar to this case... And that's debatable.
I use GrapheneOS, and I think police profiling people based on phone model is bad. But government profiling based on skin color or other effectively immutable, born traits for enforcement of law or policy is so much worse.
The notes were different but the chord progression was the same.
I don't think wildly inappropriate heuristics for the treatment of others is particularly distinctive of Americans... Even and maybe especially odious racial heuristics are not distinctive of Americans. Everywhere else I've been in the world, the racism that rears its ugly head there is way more blatant and open than what I've encountered at home. It just does so less often because there is more demographic homogeneity in other countries.
Having heuristics derived from evolving in small groups for a very long time (which are inappropriate in the postindustrial environment we have fashioned for ourselves) seems like more a human characteristic than an ethnic or national one.
As for whether it's worse in other countries... I don't think you get to make that determination without being a visible minority. Certainly, ethnic violence and racial violence are akin but not the same, just as treating people as second-class citizens based on the color of their skin is akin but not the same as treating customers as second class citizens because you don't like the strength of their OS's security standards, or don't want to hire Android programmers, or whatever.
