> Most people are not going to be finding surveillance bugs in their homes or offices.
Sadly, hidden cameras, microphones or other forms of espionage in the workplace are rare but not unheard-of in the recent past, e.g. Wal Mart [1] or Lidl in Germany [2]. Any shop with a tradition of union-busting I'd assume to be filled with all possible sorts of surveillance by default. On top of that come the sex pest cases like [3] - and these have exploded in the last years now that tiny bugs can be had for tiny amounts of money on Alibaba and whatnot.
