If anything it's far more dangerous tech due to that. Let's say you live in 304; They know who lives in 303, 305, 203, 204, 205, 403, 404, 405, and the likelihood that your neighbors aren't as tech savvy and use ISP provided routers and modems means that they can use all of those sources to create a 3d image of you and your apartment with the proliferation of 2.4ghz and 5ghz to create a high resolution image that can track your lip movements and even your keystrokes on a computer. That basically just becomes a multi lens 3d camera recording at 5000 fps. The only way to avoid this is to faraday your entire apartment which ironically makes your signal much higher due to the deployment of countermeasures. The ol' "huh, interesting, what are they hiding?" approach.
