like in enterprise? the browsers stopped shipping with ftp support I think 5 years ago.

You might be surprised to learn there are dedicated ftp clients.

Hosting files to be downloaded via web browser isn’t what it’s useful for. If you’re going to do that, you might as well use… a web server.

FTP is useful for bidirectional file exchange over the Internet. There are other protocols, but they all have drawbacks. SFTP can be used for similar functionality, but it requires users to have SSH access. SMB and NFS don’t really work so well over the Internet and are a pain to configure for multiple users. For setting up accounts dedicated to transferring files, you really can’t beat FTP (or really FTPS, which is just FTP over SSL).
