The part that bothers me the most about OneDrive is that it redirects the users Documents/Downloads/etc folders to its own entirely breaking stuff (and making it painfully difficult to find where files went because either it's in Documents or Documents which are entirely different directories on the hard drive of course. This is particularly agregious given Microsoft already has a really well-made shadowcopy/file history solution which lets you restore files or grab old versions of files straight from the right-click menu. So if OneDrive was simply an optional filehistory endpoint it would be far less reviled. Instead they do this ass backwards redirect that kinda works but makes a mess of things once software not made by companies named Microsoft enters the picture.
