1) A big thing is trust - people trust Apple to keep their data secure much more than they trust Amazon, especially when you contrast both company's main business model.

2) Apple's "Find My" was pitched first and foremost as a feature and benefit for the user. And the value proposition was very clear and useful from day 1. You can find your lost phone even in a place there is no signal. Now with Airtags you can find any device. It's easy to imagine a horror story where you lose your $1000 phone in a basement bar or drop it in a parking garage somewhere. Apple in general has better PR.

3) No one's losing their Alexa device. I mean for 99.99% of users it's never moving once it's placed. So what's the point of this feature? It's just pure revenue gain for Amazon with like zero benefit to the average user. They want to use our wifi purely for their benefit? Come on. I know there is Tile functionality, but it's still creepy - you're using my _home_ as a tracking beacon? At least when it's my phone, I'm on the move and could be anywhere.

Just to expand a bit on the last point - the way Apple's "Find my" works is that the only information shared is that there was an iPhone at some location and crossed paths with a lost item at that location. The way Amazon's Tile will work is that a lost item is crossing paths with an "anonymous beacon" which happens to reside in a very specific location.

In Apple's implementation, there is almost no way to personally identify whose iPhone made the detection. In Amazon's case, it's trivial to identify it - it's the beacon that's at the same place all the time, which happens to be your house.
