It would be reasonable to:
- factory reset the device before unlocking it to protect existing data (like Android phones require)
- display warnings, for example "if someone's asking you to do this, it's probably a scam"
- for the owner to be allowed to permanently disable unlocking, e.g. the commonly cited example of someone setting the device up for their elderly parents
This opens a wormhole that warps us back to one of the core issues / battlegrounds in computing: ownership, and specifically, the balance of power and responsibility between the owner and the user, when they're not the same person.
Unfortunately, the same means and the same arguments cited in case of "someone setting the device up for their elderly parents" also apply to employers "setting the device up" for their employees (where "setting the device up" may just mean letting it access the company network), vendors "helpfully" "setting the device up" for the customers (this is basically the whole history of mobile phones - bootloaders now, SIM locks before), etc.
I don't know what the good answer is. I'm personally strongly biased towards "end-user should always be the owner" perspective, and while I recognize there are strong examples where this isn't the case, I can't figure out how to cleanly separate "legitimate interest" from for-profit or for-power abuse.
And while we're at it, let's not allow apps to refuse to run because of rooting.
I think it's pretty consistent, whoever legally owns the device should be allowed to decide what is and isn't allowed to run on it.
I never understood this point. From what threat is it protecting the data from? Surely a thief should not be able to unlock a device without first typing the correct pin/password, and it they can do that they should be able to access the data regardless.
There have been times when I really wished that I could OEM unlock my Android device without wiping but overall I think I sleep better knowing that my PIN isn't sufficient to extract all of its data.
Making laptops that weigh two pounds instead of 40 pounds could make it easier for thieves to steal them. Making computers less expensive could increase the number of spammers who can afford one and make it easier to send spam. Making encryption widely available could make it easier for bad actors to communicate.
But these things have countervailing benefits, so we do them anyway and then address the problems by a different means. When someone insists on doing it in the way that "incidentally" provides them with a commercial advantage, suspect an ulterior motive.
Ahh, if only governments would start cracking down on scammers.
Alas, scammers are a feature of modern capitalism. You'd not be wrong if you thought modern businesses are built on scamming people.
Making it easy to unlock could make it easy(er) for scammers to get it unlocked:
> I received the same type of call a little later in the day. They were very adamant they were calling from the Bell data centre, on a terrible line and I made them call back three more times while I considered their requests. They wanted to have me download a program that would have given them controI of my laptop. […]
