Clearly Find My iPhone needs an update. But I wouldn't argue that they should make AirTags less secure because something else is also less secure.How is that different to the current situation where I can view my wife’s location via her phone?
If someone can get hold of their partners phone to allow sharing of the airtag then they could just have easily done that for their phone or watch ages ago.
This is where the security comments don’t make sense to me. Family sharing already shared the location of your phone and other devices. If security is an issue for airtags then why is it ok for the other devices.
