I acknowledge that some legitimate business telemarketing exists.
I can’t remember the last time I ever encountered it.
The last several thousand “telemarketing” calls I’ve got are from “cardholder services” trying to get me to hand over my credit card info so they can steal my identity. “Microsoft support” trying to get me to let them VPN into my PC to steal my identity. “The IRS” for stealing my identity.
Occasionally I’ll get political campaigning robocalls. Paid with PAC/SuperPAC money I don’t agree is legitimate anyway.
I don’t begrudge actual telemarketers. They barely exist. They’re not the problem I’m talking about, I doubt anyone here thinks of some down on his luck guy selling vacuum cleaners when they hear “telemarketer”. They’re remembering the guy who got their grandma to buy fake life insurance.
