When we launched our anti-theft feature, we were clear that if we found there was widespread abuse, we would change course. We have had literally zero complaints of anyone being stalked with a device where anti-theft was enabled.
And I think you are misunderstanding the new standards. Google and Apple will proactively notify thieves of nearby trackers, and allow a thief to disable it. This is next level bad for anyone relying on their tracking device to protect against theft.
What is the data that would change your mind? I would change my mind if we found that more than .1% of our customers were abusing this feature.
