This gives me an opportunity to rant about Apple, in regards to another self-serving, money-grabbing practice. I bought an Apple Watch from the local state government surplus. This is a place where surplus government property ends up when it is no longer needed. It is also where stuff from airports ends up - items that were confiscated (knives, corkscrews, toys that look in any way like a weapon, and other "dangerous" items) and stuff that was lost and never claimed.
I bought the watch knowing it may not even function (although it looked to be in perfect condition), because they did not have the means to charge and test it. They just liquidate whatever comes down the pipe. So I charge the watch and pair it up, and find it has an Activation Lock on it. Now this is a watch that sat at the airport for the prescribed legal amount of time and was never claimed, and then it went to the state level where it was also never claimed. So many months later (or a year or more - it's first gen watch) it was legally sold by the government to me.
So I came to a realization. I have no way of contacting the original owner. I can see that they have a gmail address, but Apple will not show the entire address. Apple will not contact them on my behalf, or otherwise do anything for me to get this watch back into their possession. I cannot use the watch. No one can (I spent a lot of time searching, and there is no way to circumvent at this time). In January Apple removed their online tool that lets people check if a phone or watch has an Activation Lock, so there is not even any good way to know a used Apple product of these types are usable.
So who does this serve? That's easy. Apple. Because I cannot get the watch back to the person who lost it, and because I cannot use it, this watch has been taken off the market. Each instance of a product taken off the market is one that does not complete against the sales of new products. Imagine if iPhones and Apple Watches could never be resold - it would result in a huge increase in sales of new devices (which are the only ones Apple profits off of directly). That is what this accomplishes, because you just never know if a used device is actually usable. It pretty much shuts down the ability for private individuals to resell on Ebay or any other way online that cannot be finalized in person, where the buyer can check the device before they buy it.
Sure, as a side affect, perhaps this reduces the theft of devices to some degree. I argue that is merely a minor side affect. Thieves are going to grab any device they have a good opportunity to take, because it could be an Android phone, or maybe an iPhone that was not registered with iCloud's Find my Device. But I argue the primary purpose is to increase Apple's profit margins further by "destroying" a significant number of devices that cannot be used by anyone else.
