Look at the link - does it have a token on it to identify that particular survey invitation as the one they sent you? I’d wager that’s what happened rather than it being some deeper tracking. A stock standard survey monkey survey can do the same thing.





Requires a cellular data plan to operate, which is where that expensive operating cost comes in. For a family dog, I could see the expense being worthwhile, but for a number of things (wallet, keys, purse, backpack, etc) that AirTag tracking typically targets as their use case, this would get quite expensive rather quickly.
