If it has no impact on you, why would you want to opt out of the airtag tracking?

If you were known to be the only person who frequents an area, then an adversary's Airtag planted there getting updated would notify them that you were present.

Are ya'll trying to invent the dumbest sounding scenarios or is that inadvertent?

In this extremely specific case where people are planting airtags to track you, you can simply disable the feature as the parent mentions.

"I don't use that freeway so I don't want to pay for the maintenance"

Either you use the roads and pay for all the roads or you don't.

That's a terrible analogy. I don't allow android devices to use my "ios roads" as it is. Why does it matter if i don't want airtags to mooch off my network? It's not like airtags are providing their share of network back to me.
