Badger your city council, work with like-minded residents in a way that can credibly threaten their re-elections, find and support privacy-conscious candidates who won't sign-onto Flock's agenda, create ads based on council meetings when councilors support surveillance in a way most voters will reject. Put their quotes on billboard with their picture, etc
Ok, you do all that work at home and manage to block flock in your area. It doesn’t matter because the next city over where you work installed them so you get tracked anyway.
Then 2 years later a new city council gets elected and they install flock cameras in your city too. You can never get rid of them because it already passed and nobody wants to relitigate the same thing every couple of years.
Local politics does not work here.
