For now you can just use FTP.
BTW, I never had to do anything like turn anonymous ftp access on and then off, to get mine to work. It worked normally for me. I actually figured out a hack to control the ftp access from the shell (different from my sftp hack). Basically, I have restricted ftp access to USB drives to specific users, which otherwise by default get opened to all ftp users, just like the Public share.
As for sftp/ssh, it was my hack about sftp that you must have seen ( http://community.wd.com/t5/WD-My-Cloud-EX2/SFTP-possible-on-EX2/td-p/715812 ). Yes, that hack is safe but isn’t that easy to do. I seriously doubt WD will implement sftp, but encourage you all the same to vote on the feature request for it.
