Actually, there are some Asians who may prefer to use European phones because there are fewer restrictions and less advertisement. 
Additionally, using European phones like the Fairphone tends to have fewer strange issues. 
Sometimes, considerations should not be limited to just hardware specifications. 
For example, some other phones, performing tasks like rooting or unlocking requires an exam – quite strange. 
After passing the exam, one could potentially apply for a position in mobile development. It is just a joke. 
I think due to the need to ensure that the person unlocking the phone is indeed a developer.
