Any discussion about this is shut down. I just read an article https://www.bbc.com/news/articles/ckqxvy98x578o In the UK according to the BBC, politicians are pressing Samsung and apple to make stolen phones bricks. Samsung in response said that they have implemented several security features for this purpose. I think Samsung considers removing OEM unlocking a security feature according to the bootloader unlock hall of shame.

Intel used to do the same with their anti theft technology aka Intel theft deterrent on their classmate PCs, so students had to enter unlock codes from an IT admin every 3 months or every say 200 boots to prevent the computer from being locked at the bios level preventing it from booting an OS, and there was an update which disabled that functionality permanently. And you would be warned when you had around 50 boots left to get the unlock code.
