Ok, so...

TV phones home a lot, with info about stuff, some info big lots of bandwidth.

could there be an attack with buying some tvs and putting them on public WiFi - and could one find a way to increase the amount the tv was sending so it amounted to an attack - but still have plausible deniability.

If tvs were put on public wifi, which I guess there is no reason why you shouldn't put your tv on public wifi, and the tv is using lots of bandwidth, and your tv is popular in a country with lots of free wifi, is that tv manufacturer guilty of an attack on the free wifi infrastructure of that country?

I'm asking for a short story or several I might write some day.

Also maybe I'm mistaken, but don't most modern cars have a built in modem for sending telemetry to the manufacturer as well?

Yes. Toyota seems to like putting the transceiver behind the glove box, forcing you to introduce a bundle of rattles to your newly purchased vehicle to remove. Also, I'm pretty sure removing it disables some of the front speakers, requiring manual wire connecting to get them back. You could maybe leave the device in there but encase it in a Faraday cage, but still rattles are introduced.

Ford, iirc, places it on the floor under or behind some seats making it much easier to deal with.

I think MA just passed a law about not allowing vehicles sold there to sell your telemetry data or something.

i believe they just have to share the data with others, which they don't want to do.

Whispernet is dead from what I understand. As countries began shutting down 3G networks, Amazon was no long able to get connectivity at a price point where it was economically feasible.

Not dead, just replaced.

Why not use helium network?
