Verizon,

  Why is the bootloader locked on my fully paid for Google Pixel 5 phone. Its my phone not yours so why cant I unlock the bootloader. The same device purchased through the manufacture doesn't have the bootloader locked so please I am wanting a real detailed answerer to why do you feel the need to lock this device. Also how do we get the bootloader unlocked and i don't want to hear we cant cause if that's the case you will loose my business
