Well, that is not true with respect to the crypto based systems which I
have looked at.
For example, David Chaum's system based on visual encryption
There are certain practical issues with this system, but it
categorically does not depend on the system acting
as a faithful agent of the user with respect to encrypting, recording or
displaying vote data.
Chaum has come up with another system more recently
(http://www.punchscan.org) which apparently
addresses some of the usability issues with his previous one. I haven't
looked at it yet, so I can't comment on it.
