Unlock Bootloader (Read-only)

USA TMO LG V20 fastboot commands
zeruth
Let me reference this page:
http://developer.lge.com/resource/mobile/RetrieveBootloader.dev

and I quote:
"Your phone will reboot into the fastboot mode. You can check if the device is successfully unlocked, you can check by entering "fastboot getvar unlocked" and verifying that the response is "unlocked: yes"

You can now download a custom android binary.

1. Run the desired fastboot command.
*Quick Guide
i. flash : fastboot flash
Ex) fastboot flash boot boot.img
ii. erase : fastboot erase
Ex) fastboot erase boot
iii. reboot : fastboot reboot OR fastboot reboot-bootloader"


Except when a fastboot flash command is called, it throws an unknown command error (LG removed fastboot commands phone side)
Can someone from LG explain why the fuck we can unlock our bootloader , but can't use fastboot commands?
