Agreed, but even for the three name servers you do fully control,
client queries pass through a lot of network infrastructure you don't
control.  Man-in-the-middle attacks are of course a concern too, but
you can at least limit your vulnerability to them by reducing the
number of third parties your zones on.

(The gold/silver stars are just something of an in-joke from work anyway.)
