I'd seriously hope those (very serious) people use SFTP, at least.
It isn't dead and yes, of course, I know the difference between FTP and SFTP.
(To be clear, I'm talking about plain vanilla RFC-959 FTP. Yes, you can add additional security layers on top. Sadly, at least the places I've seen still use FTP are the places that still use it in vanilla config. I have no idea what your experiences are - this is a comment on the general state of FTP users.)
Stop doing this people. There are far better formats than FTP, and yes, even better and more appropriate than SFTP.
(Further, even if Drive supported it, are y'all going to be uploading your private keys to Drive?)
