And yet they are removing command line utilities... High Sierra just removed 'telnet' and 'ftp'. Crazy that Windows ships with a telnet client (you have to enable it, but it's in the standard distribution), and a UNIX-derivative like OS X doesn't.
Why not remove netcat, as well? It opens unencrypted sockets. Or perhaps wget, since it lets you download unencrypted http? Even git has a built in ftp client.
There's nothing at all obsolete about ftp or telnet. They both implement their respective protocols fully and properly.
New devices shouldn't implement ftp or telnet, but that doesn't mean that having the ability to connect to them is no longer something that happens.
