When we deployed O365 to 100k+ people, we ran into a few things like this.
A big one was the meaning of "everyone" in OneDrive. Many people thought that it meant "everyone on my team", and posted all sorts of wacky stuff.

No one in my building uses one drive, no one asked for one drive but Microsoft keeps trying to shove it down our throats. It feels like an anti-pattern like the forced windows 10 "upgrade" for home users.
According to word I have Office 365 ProPlus version - I note there is no option to save to docs.com.
I encounter many co-workers though who like to do things "the old way" and just email copies of documents around and then spend time merging them back together instead of sending a link to their OneDrive. Just more files for me to juggle on my computer. No thanks.
Partly because I need to access stuff offline so prefer to have a local copy. For example if I have to take my laptop travelling with between sites I may not have access to a internet connection.
Your right that a large part is familiarity - we use Sharepoint (which I also hate) to share documents between teams rather than email.
You missed the serious suckabe. 3 years ago you could put the sync client on a fresh install of Windows 8 and do nothing with it and it would break itself.
