I bet if you tallied it up, there's many more people being tricked into taking on bullshit contracts with legitimate companies[0] and losing much more money in total, than there are victims of actual impersonation scams. I firmly believe both schemes are morally equivalent, and that one of them is still considered legal only means we should push firmly for a change in laws.

Even the impersonation angle isn't clear-cut. When a telco calls me with their newest scam, it's always via a third-party call centre they outsource this job to. Where I live, it's also historically has been a major source of contact and personal information for scammers - always a "disgruntled employee" leaving and "covertly" taking the customer database with them.

[0] - Telcos are my go-to examples here, they're notorious for borderline fraud. For example, just under a year ago, a billion-dollar telecommunications corporation named after a color, one of three major telcos in my country, tried to scam my own grandmother hard, after my grandfather passed away, and almost succeeded. More generally, after many years of near-misses and one or two mistakes, most people in my family learned to never talk to phone companies cold-calling with offers.
