Hey, no one is trying to stop you from doing that. I'm sure it is very convenient for you.

My point of view though is that automatically uploading my personal files to some corporation computer on the other side of the world should not be the default when I try to save something. Maybe sometimes I'll want to use that feature, but there are a variety of reasons why I don't want it most of the time. And I definitely don't like having to jump through hoops just to avoid it.

We used to do this with thumb drives. You can get a 128G usb3 thumb drive these days for like 20 bucks in the checkout line of most electronics stores. Cool things about a thumb* drive is I don't need to pay a subscription fee for it, it doesn't need an Internet connection, and it isn't liable to be rifled through by Microsoft unless Bill Gates comes to your house and steals it from you.
