> To add injury to insult they made OneDrive the default way to save files in Microsoft Office, but sometimes a problem with OneDrive would mean YOU COULDN'T SAVE YOUR WORK AT ALL.

It's worse than that. The change to default OneDrive breaks auto-save everywhere that isn't OneDrive. On the Mac, this includes breaking auto-save on pre-Azure Sharepoint instances and network shares, but some of that works sometimes on Windows. So Office is a worse product even if you never use OneDrive.
