With cameras and motion sensors you more or less know how they'll be used and as a user you can choose to disable them (or at the very least block them if you can't disable them).
With this technology, it will be integrated into your router (and clients?), so turning those off will mean to turn off WiFi altogether. Added to that, I'll bet that most people wouldn't even begin to imagine that WiFi could be used for sensing people, and they'll continue using WiFi without being aware for the grave privacy implications.

It's rather unreasonable to think that you won't be able to turn off band on router. Especially given fact that 60Ghz is heavily shielded by _doors_, so any usable router would require fallback 2.4/5/6 Ghz connectivity.
802.11bf Wi-Fi 7 Sensing works with all frequencies, 2.4 and up.
Even if Neighbor 2 turns off their router, Neighbor 1 could passively use the radio waves from Neighbor 3's router to surveil reflections from Neighbor 2, including keyboard typing, heartrate/breathing, location and physical activity.
This is hyperbole. 60GHz cannot penetrate walls and closed doors. 2.4GHz and 5GHz lack the resolution to image you, especially if your adversary only has control of one AP. There are already tons of side channel attacks with existing WiFi and Bluetooth that reveal when someone is in the area. Your neighbour could already be tracking your devices, for all you know.

There's no reason to assume any of that.
RF is far less hindered by stuff like walls.
Your next door neighbor’s wifi will know your every movement, and can probably image it too. End of privacy within closed doors.

Do you have those at home?
