Anonomus FTP is also still valid for downloading public files from a public 
FTP file server.  Otherwise, yes, FTP should not be used for anything else.  
There is no longer any valid reason to.

All tools which used to use FTP (eg HTML editors and the like) now all suport 
sftp, which is imlemented in the OpenSSH server, which is installed by default 
with most Linux dristos (or can be trivially installed on all Linux dristos).
