"People section" turning on by itself and digging into my old photos without permission

I have used OneDrive on Android for years and just now I had a notification appear with an old picture of someone in my family asking me to type in her name and if other pictures of her are also her. I was shocked and irritated at this apparent privacy violation.

I found out a "feature" called "People section" where "OneDrive uses AI to recognize faces in your photos" just turned itself on and decided to send me a notification.

How utterly irritating. Microsoft should understand how unnerving it is to have your phone seem to just start digging into your photos without your permission. Why couldn't it just have a notification asking me if I want to turn on the feature and explain what it is? Why show my personal family pictures?
