Re: What exactly was the point of Kirk's "Stop Energizers" command in
Maybe because the intercom system is wirelessly networked to the combadges?
Or because standard 24th century eavesdropping methods include tapping into wired communications, either by some analogy of today's "point a sensitive rangefinding laser to a window and use that as your microphone diaphragm" technique, or then by the use of nanoscale physical tapping devices. Some variant of the former allowed Spock to tap into a Romulan CCTV system in "Balance of Terror", and I can't imagine such a system actually transmitting anything radiatively (Spock just "locks on" to some other transmission coming from the ship and then slithers in using some techno-mojo of his to see things that are not being transmitted at all.)
Picard might well assume his ship to have, oh, about sixty million Romulan and Ferengi bugs aboard, with standard countermeasures in place to prevent them from transmitting their findings, to feed them disinformation, to hunt and kill them with counter-nanites or whatever. He would just assume that when encountering a superior opponent, this level of counter-activity would become insufficient. So it's back to basics - running messengers and the like - until the enemy shows his hand on whether even this is insufficient.
How using printouts from printers that handle data via wires, no matter how locally, would be safe in those conditions is unclear.
It actually made sense to me that the naval tradition of calling the directional thrusters the 'rudder' would continue to spacefaring vessels of the future.
Ships on the surface of a body of water can turn in two directions, on one axis (port and starboard, or left and right rudder), and translate along one axis (fwd/aft). Spacecraft can turn on three and translate on three - and Trek ships have at least three distinct propulsion systems for doing so. It might indeed make sense to have boatlike behavior described in seagoing terms and un-boatlike behavior (such as moving sideways without turning) described in new, more appropriate terms - as different-sounding as possible to avoid confusion.
It might actually be very rarely that a starship would have to mind "rudder", which would be a command about turning the ship relative to her current line of motion (be it left/right or the more futuristic up/down). Normally, Kirk would simply want to point his ship towards a desired direction, which would be accomplished by stating out that direction (xxx mk yyy) rather than micromanaging rudder settings. But when matching course with the Klingon ship in ST6, direction is secondary; orientation is paramount.
(Of course, "right standard rudder" today would mean something like "turn to starboard with the greatest efficiency and angular speed short of emergency setting" which is a funny thing to do when
fine-tuning your attitude during a close encounter! But perhaps Kirk wanted to show off; near-ramming of the Klingon ship would be just the "Nixon in China" attitude Starfleet was expecting of him.)
