Take for example, if Samourai Wallet was being designed by a black man somewhere in Africa and the platform was open to be used by anybody around the world (across other countries), can the government still shot it down?
They can shut it down so long as they believe the platform is being used by the criminals they hate the most, such as those North Korean hackers, to "launder" money through it. it doesn't matter where the platform was created from or who created it. They will work so hard to sanction it and then probably seize it.
Centralized platforms are so prone to such a thing.
