The ability to lock stolen phones should be under the control of its owner. Keeping it under OEM is just asking for that capability to be abused and misused against the wishes of the owner.
How do you keep that only to the owner without proprietary software Should only the owner have a private key? And how would it be set to be the correct one in the first place?
I don’t understand the requirement for a proprietary software for this. Meanwhile, boot chain verification exists already. And there is no reason why it can’t be under the control of the user - with a user-supplied private key.
Free software should be able to be replaced by anything - by the owner. There is no technical reason the device can’t still be locked to prevent modification by someone else. There are already free software that allows you (the owner) to remotely screen-lock the device.
