This is similar to Flock and Palantir who collect info the government is not allowed to and then sell it to the government.
In this case Meta, Google etc can honestly say they aren't surrepticiously listinging to you or collecting data not in their privacy statement. They just buy it instead.
So I need to write a chaffing agent that runs when I am not home and randomly spouts synthetic conversations through non-smart speakers about nappies (kids a re long gone), nuclear weapons development, plumbing, union membership, crochet, video games, crypto coins, and other things we don't normally do.
