I haven’t seen any evidence relating to your claims and Air Tags. Perhaps other makes do as you say but Apple take security seriously. The data link between Air Tag and Find My App is encrypted so I’m surprised at your claims. Here’s a statement from Apple relating to Air Tag security and features.The air tag will pass on the data of your location which includes shops you visit etc. The next thing you are being bombarded with adverts for other shops selling similar stuff to the shop you visited!
No thanks as it is bad enough at present being constantly tracked and your personal shopping habits being identified. In addition, it will pass on the data that you have left your home and possibility no one at home.
An update on AirTag and unwanted tracking
Apple announced it has identified even more ways to update AirTag safety warnings and help guard against unwanted tracking of people and property.
