OpenWRT routers are the solution. Can't track you if there's verifiably no code to track you.
As for the neighbors, that's a tougher but to crack.

your neighbor will pay premium for the new "security" feature, that the router alerts him if there is movement when he is not at home. he won't mind that the raw telemetry is streamed to the manufacturer's cloud 24/7.
I'm moving to the country personally. It's about all I can do on my end. Unfortunately much to financially taxing of a solution for most currently.
