Technology

One aspect to consider is exactly what data these devices are exfiltrating from your network. You usually can't see the contents of the telemetry sent, but given that a LOT of smart devices have cameras and/or microphones, do you really trust that your IoT devices are not sending back audio and or video recordings of the inside of your house?

A detailed room-mapping scan is basically a wealth report disguised as vacuum telemetry: square footage, room count, layout complexity, “bonus” spaces like offices or nurserie; all of it feeds straight into socioeconomic profiling. And once companies have that floor plan, they’re not just storing it; they’re monetizing it, feeding it into ad networks, data brokers, and pricing algorithms that adjust what you see (=and what you pay) based on the shape of your living space.

And a mapped floor plan also quietly exposes who lives in the home, how they move, and what can be inferred from that.

And just like that, my $300 smart vacuum transformed into a mere paperweight.

First, it isn't a roomba, second it says in the article how much it cost, third some people have hobbies and sometimes those hobbies are tinkering, dismantling and hacking things they supposedly own and that sometimes leads to revelations like this. Hope that helps.
