I use macs as my daily drivers and have no idea what you're talking about? Don't even have to sign into iCloud to use it

You don't have to use it, but iCloud Drive and Sync is a fairly commonly used feature:

> Desktop & Documents Folders: Keep your Desktop & Documents Folder in sync with iCloud and access them from other devices and iCloud.com

But easily has issues reconciling files on different devices, and then, if you turn it off, things get messy and need a lot of moving things around.

Makes sense. I generally avoid anything Apple Cloud related; those products are not their strength...
