I find intriguing their explanation about how to use their FTP service and why it’s not possible to access it with a modern browser.

They make an (easily made) mistake on that page: the encrypted version of FTP is not SFTP, but FTPS. SFTP is an entirely different protocol based on SSH.

HTTP to HTTPS is FTP to FTPS.

"cp" to "scp" is FTP to SFTP, i.e "secure" prefix.
