Assuming you get boarded by pirates, what happens next? Why would you need a bridge that could command the ship? Even if you did, turn it off unless you can remotely switch it on again. How much damage can pirates do to an empty ship? Plus, no hostages, so there wouldn't be much stopping armed forces going in guns-blazing.

Disable the ships communications with jamming device. Tow it to port, hold ransom for % of cargo, or sell cargo in the local market.

Is "towing it to port" really something that is that easy to do? These are big ships that are probably not easy to make disappear. Also, without hostages, using armed forces to take the ship back would probably be a lot easier.

Finally, depending on the cargo and location, I would imagine selling off the cargo would be a simple matter.

Still sounds better than doing the same thing, but with a crew on board.
