Earlier quoted context omitted.
AirTags are not better in one very important way: they don't prevent theft. They will notify thieves that they are hidden in a valuable item that they are stealing if the thief carries an iPhone. Tile has a feature where you can submit your info and sign some sort of extra contract stating that you won't use your Tile for stalking/illegal activity, and you can actually hide a Tile in your bike frame and it can be use…
How do hidden trackers "prevent" theft? If a thief steals your bike and is notified that it's being tracked, they're probably much more likely to abandon it somewhere, at which point you can recover it. This seems like a safer bet than trying to hunt them down yourself. (It should go without saying the police are not going to go get your bicycle back for you even if you do hand them the GPS coordinates.)
Also, the attitude of “don’t go and get your stuff back yourself, it’s not safe” is just castrated cowardice and only emboldens thieves. Thieves should be afraid of both law enforcement and vigilante response. Better society when both are on the table.
