Not bad for throughput increases, though most of the increases come from more spectrum, and the reliability comes from more MIMO antennas/streams. I've had WiFi 4/5 2x2 routers and something tells me I won't see much more than what's listed above for 7. Buying a 4x4 does get you a generation of throughput in advance pretty much, if you need it.
Reading a website about cheese, show me a cheese-related ad, viewing the map of my neighborhood, show me neighborhood related ads, no need to get my location for any of it. These are things that a server already knows it served you, a website and a map.
The opposite of dragnet surveillance, which is what flock and geofencing warrants are: data aggregated and shared without the consent of the user, is data collection minimization even when done for security or apps.
