Yes, Amazon, I totally want a proprietary network to circumvent all my network security to go create a rogue peer to peer based network with my neighbors, that's definitely a think I would love, thank you.

I mean, what could go wrong

Ok, this is hilarious. "Benefits of Amazon Sidewalk":

"Amazon Sidewalk creates a low-bandwidth network with the help of Sidewalk Bridge devices including select Echo and Ring devices.

These Bridge devices share a small portion of your internet bandwidth which is pooled together to provide these services to you and your neighbors. And when more neighbors participate, the network becomes even stronger." There are literally zero benefits here. Zero.

They should just say "The benefit is that Amazon can control your entire house, even if you literally unplug your internet cable from your router."
