Normally I wouldn’t worry about it, Samsung just apes everything Google does. It’s part of their tug of war, basically Samsung is saying “if you ever pull a Huawei on me and disable every Google feature I’ll still have a copy of everything”.
Then again the US market is wierd so I don’t know. You can unlock Sony bootloaders everywhere else without a hitch but they cut a deal with US carriers so they won’t give unlock codes to US models. If Sony did deals like that so can Samsung.
