The movie is actually pretty good!
there was a post a while ago about amazon ring and other devices setting up a mesh network for themselves using your wifi.
I still do not think this is a bad thing necessarily as long as the functionality is documented and user controllable.
the main problem is people not understanding what they and their devices are doing.
I am not saying people are stupid, but they are uneducated.
I consider myself uneducated on many subjects but still I increase my own education every day.
