I don’t think Tile cares about privacy.
Tile doesn’t have a network of devices chained together. So once it’s out of range, it’s essentially gone.
These trackers are indeed not anti theft solutions. They’re to help you find your keys or wallet, etc. I plan to stick one to my itty bitty Apple remote.
I’m sure airtags could theoretically help but once thieves find it they’ll toss it. Or the ignorant ones may think, hmm apple? Expensive! Hang onto it until they figure it out or maybe the owner luckily locates them.
