I spent 24 years in the Navy so I look at things as a sailor.
I live in a rural area where internet is intermittent. I also travel with my husband and can spend the entire day without the internet.
It is bad enough fighting updates because of internet access and having spend months at sea you can't bring the internet up on your computer. Using a government computer to access the cloud and work on something personal can get you into serious trouble. If you are a junior rank you are looking at email only when at sea.
As a writer and having recently synced to ease the back up of my laptop that I need to send in for warranty repair. Now I am finding accessing my files difficult if not impossible off line.
Syncing should never mean that I can't have access to my work.
The inability to easily turn syncing off shouldn't result in loss of all work when you delete files from your laptop prior to sending it in for repair.
Syncing shouldn't require you to know computers to be able to tell the location of a file and ensuring the file is stored on your physical computer.
Syncing should be designed to allow you to keep certain personal files from EVER being synced because the only true way to protect data is to have it on a external hard drive that you only access when you are working off line.
I really wish Microsoft would remember that not everyone works in an office building, has internet access all the time. Maybe their programmers and developers need to take a little time off and go camping and while camping see what works and doesn't work. No cheating with mobile hotspots on some expensive phone.
