The NDAA blacklist was a happy compromise by the US government of banning the most egregious vendors that might find their way into sensitive facilities (Huawei, Hikvision, etc) while letting consumer focused brands that do the same (TPLink, Jetstream, Wavlink, etc) slip by so it didn't appear at face value to be a blockade of all Chinese made networking gear.
