Cons
Con No official GUI
To use rsync, you have to know your way around the command line.
Con Complicated, and you can accidentally overwrite the wrong files

Con No client for Linux
No client for Linux.
Con Old versions and deleted files aren't available online, just on one computer.
On some other services you can see previous versions and deleted files for a time, but with OneDrive, these are only available on the computer the edit was made. So if someone who has write permission on your shared folder deletes your stuff you just have to ask them to go in their recycle bin (and hope they didn't empty it!), which makes it less useful for teams.
Con Online OneDrive are slow
Compared to other cloud storage, the web interface of Onedrive is slow. It got a slight delay on every action like opening a folder, delete, etc.
Con Recycle bin doesn't support replace
Imagine you have 100 folders to be restored, and they cannot be restored because existing folder is already in your main folder and you intend to overwrite them but they don't support it.
Con Time limit for inactivity
Based on OneDrive's terms of service, no account login within one year will be automatically terminated.
Con Strictest code of conduct
Terms of Service forbid any kind of nudity, or that incites, advocates, or expresses pornography or racism among other things.
