Have you seen those GoDaddy commercials with Danica Patrick? Those commercials appeal to people who, I'd gander, have a lot more to lose (and aren't as wise to the potential sly tricks... of the internet) than what could be phished over the phone from your telco provider.
Not in the US, so I don't see that ad. Good point about lot more to lose, though I wonder if 2FA through phones makes losing phone access a risk as well.
Not much different than looking up someone's whois and pretending to be GoDaddy.
