Nothing is necessary of course, it’s just to counterbalance the ‘hurr durr Apple bad’ crowd which seamlessly gaslights between ‘AirTags are terrible stalking devices and Apple is responsible for all stalkers and stalking wouldn’t be possible were it not for the terror of the AirTag’ and ‘I don’t care about privacy and why is Apple giving these stupid notifications to counter stalker use of AirTags.’

There’s tons of tracking devices on the market and Apple made choices to make the use of AirTags private and with a certain level of protection against stalker use. It’s known before you purchase them, if you don’t like it, don’t purchase them.
