The worst part of this is, if you don’t have an iPhone, you’ll never know if you’re being tracked.

Edit: Yes, I know there’s an app. Do you think more than 1% of victims will have it installed?

There is, it's open source and works. I have have this running on my phone in the background and it has alerted me a few times like when my phone was in the locker at the gym and someones airtags was in a locker close to mine.
