If the government can force a plumber to that, can they force the plumber to show up to the job on time? Will I be charged for the extra time? ("Hey honey, the plumber picked up my call on the first ring. Is that suspicious?")
Paying the plumber or janitor to spy is as old as dirt.
Hell, I remember a proposal to encourage that during the GWB administration for “terrorism”. I wish I could find it, but Google is incapable of returning anything from before 2023 any more.
