Same thing there. It shouldn't matter if the tech is possible, produced, cheap, and installed in your home.... it's all moot if the act of the surveillance isn't followed through. We need to work towards ways to prevent the acts themselves, as we simply aren't going to be able to prevent the possible sidechannel attacks from being possible. They are always possible.
Wi-Fi access points are often provided by ISPs. ISPs, especially in the US, are not to be trusted; https://security.stackexchange.com/q/71834 is just one example of that.
Nope, remote sensing only requires custom radio firmware on the passive surveillance receiver that is monitoring Wi-Fi reflections from standard consumer routers which are "near" the target.
People have no idea how much debt Police depts (lets not even talk about the military) have racked up playing with high tech toys and paying off compensation every 2 days for people they accidentally harm or kill. So whats funny here as Big Bro gets access to more and more tools the more broke he gets.
And guess what the financiers of this debt will do when it cant be paid off. Raid police pension funds. Thats how financialization of public service works
No free lunch big bro. Have fun with all the "cool toys" while the good times last.
possible -> prototype -> product -> common -> common and cheap
If Wi-Fi surveillance were to become common and cheap, other methods would be produced to make data harvesting common and cheap to the surveillance state/bigco. The best way to avoid that dystopia is to safeguard it early in the process.
