Because Internet Explorer 5 does NOT use PASV by default any more;
it defaults to PORT.
That is:
* If you set IE5 to display FTP as a "file explorer", it uses PORT.
  This is the default mode.
* If you set IE5 to "display FTP as a web page", is uses PASV.

Probably some geek coder thought "ah you can be active with file
explorer so we'll use active mode, while web pages are pretty passive
things, so we'll use passive mode".

Duh.
