For any such feature on such devices, it would be more honest for the
purposes of debate to state that as "Some customers want these features
[...]" which is completely true.  

There are a lot of features in a lot of devices that are never used by
(a few, some, most, etc) end users, and even where they are used, the
existence of web or ftp services on a storage appliance may merely mean
that a user finds it more convenient to access the device locally that
way...  rather than setting up SMB etc.  It certainly does not imply
that all customers who buy the SuperStorageDeviceWithFTPCapability are
running public FTP archives and that NAT becomes a problem for the
owners of all those devices.  It may be a problem for a percentage of
them, though.

With 24 million small businesses in the US alone, that's way too many apples.
