Oh please. Unless you’ve never opened system settings and got the device with a user account pre-configured for you, you have been exposed to iCloud several times.

Does it make one especially edgy to pretend to use an Apple device while never having heard the name of their single cloud offering? Whatever floats your boat, mate.

Correct. My device is issued to me by my employer. I never owned a Mac in my life.

I admit that my comment was a bit over the top. But all I know about iCloud is that it's similar to OneDrive. Never used it.
