The author makes Google look like good guys. I routinely get robo calls on behalf of Google. I really don’t believe Google is interested in stopping robo calls.
I remember a movie from decades ago how a sinister corporation had the ability to make a call and fry the brain of whomever answered with blood pouring out of their ears. I want one of those phones.
Those aren’t actual Google robocalls. Those are scammers trying to take your money and get access to your computer, just like the Microsoft scammers. Neither company will robocall you.
