I expected the article to address that. Maybe it's obvious?:

"It's for you own good. It would be harmful to disable it. And you don't understand it so you shouldn't have an opinion. I trust Apple to do this safely, even if I don't want whatever this is."

Turn off your Mac and use a different operating system. Because it doesn't matter how you disable this feature in isolation. It is merely the current projection of Apple's opinion of its relationship with you. It's a hydra and you are going to lose the fight.
