The protocol is buggy AF. All that crap about sending data over a separate TCP connection, the weird way you have to deal with state and authentication; ftp is an utter shitshow. Just because a protocol is old doesn't mean it's matured to perfection. Telnet is old, so is RCS, and UUCP. Many protocols evolve not by being replaced by incrementally better point releases, but rather by being supplanted entirely by a better designed alternative. FTP effectively evolved into HTTP for this use case, and scp/sftp for the authenticated file transfer use case.
