Indeed.
The bit, like any other piece of equestrian gear, is a tool. In this case, its the “communication device” that transmits the message of the hands to the mouth so the nose can be pointed in an appropriate fashion. The rest of the horse follows the nose. Properly used, it permits clear and concise direction. Improperly used, it can be torture device that can drive a horse into dangerously evasive behaviors. Conversely, an ineffective bit can lead to the rider having the false belief that they have communication with they really don’t; that, too, can permit dangerous equine behavior. But these last states are the fault of the rider who makes poor equipment choices.
In no way, shape, or form does “clear communication” negatively impact the “partnership” between horse and rider. Quite the contrary, it ensures that such communication is two way, as the horse can communicate BACK to the rider’s hands by how they react to message being sent. Put another way, this communication is a two way street and the clearer the messages in both directions the better will be the performance across the board.*
There is a place in the training world for the various classes of bit-less devices. At various times over the years I’ve used a bosal, hackemore, side pull, and halter with two lead ropes. Young horses, older horses needing a “restart,” horses with mouth pathology, etc. often benefit from time without a bit.
The First Principle in riding with a bit is that you understand that the true power of the bit is in the hands of the rider. I’ve used bits ranging from very mild snaffles to the M1909 Cavalry Bit in a double bridle. Had some experience early on in my Walker years with the Walker curb bit with 9" shanks. I’ve had one experience on a horse with a Shoemaker bit. My take on all this is that the bit when properly used is like having a two way conversation with your horse using a high quality, digital radio or phone. The bit-less devices all pretty much function like two tin cans connected by a string.
And I’ve also learned that when you ride with your whole body, and not just one part of it, things go better, too!!! 
Ride with what you want but understand how what you want works and what it gives and what it doesn’t give and what it might even take away.

*Note that the “two way” part of all this mostly with folks who ride in contact. If you’re on a “draped” rein there’s not much the horse can do to send a message through the rein short of vigorous head shaking.
