Just got an email from amazon about their Sidewalk rollout. They’ve really up’d the creepiness this time. Apparently all Echo and Ring devices are going to be sharing (leaking?) your home network with your neighbours.
The email I received says you can turn this off in the Alexa app but I just checked and the setting is not yet there in the the latest Android app (at least in the UK region). Nice touch amazon, send the email out before the setting is available. How many people will forget about this and amazon will quietly build a peer-to-peer network for itself. This should be an opt-in not opt-out service.
I have all my smart devices in an IoT VLAN but in a flat network (the vast majority of use cases) it could also be used to snoop other traffic in your home; what you watch on Netflix, Plex, bittorrents, where you shop, etc. It could be collecting all sorts of remote telemetry.
