The first one is about finding an AirPod in the snow. Follow the headline link to read.
But the second one is down in the comments, quoted here:
Their pods + case would always stay hidden away in their car, hidden from view and wirelessly charging for whatever place they were going to.
One day they went missing and that was that …until he was told about the Find My function.
Lo and behold, it registered in the app! And they went on to search for it.
It was at a car wash. When they told the boss about what they were doing on the premises, he went and rooted around for it himself and eventually found an employee wearing them.
Find My is brilliant.
[There is reasonable security in that you get notifications if someone leaves their AirPods near you, whether accidentally or as a spur of the moment attempt to track someone.]
