Maybe learn about directional antennas. I dunno

From who? Information online is all tainted. Nothing useful at this point. They know all and stop whatever is not supposed to be given to the public.. only way old hardware warfare. Remove chips, shortcircuit antennas, disconnect microphones and cameras. Faraday cages and rf sensors to verify real offline transmissions. So... Best choice remove all the wifi equipmenta and rewire home. Some tracts in fiber. I bet in few years Internet will be unusable anyway so storing all I need in local network and doing physical optical backups.

I built many directional antennas years ago but now the new arrays and geometries are out of diy abilities. The only way is tricking the system with shields and coaxial delay so they cannot triangulate the signal. At a certain point better to avoid the transmission and that is it. With AI analysis they can easily decode position even with this tricks. Pair car plates from cameras with gsm position and rebuild behavior.

Yup. I feel like monero has the right idea with decoys. They need to be normalized though. Today, a decoy makes you stand out as bad as a coinjoin transaction. In monero, everyone is required to use decoys.

From who? Nobody, anybody. I just want the 'reasonable expectation of privacy' bar to go up not trend down as it has since the beginning. The reasonable expectation of privacy is about zero these days which lawfare can do whatever they want now.
