>> Here's where they messed up: the orbit is backwards. Clicking and dragging has very well defined behavior: if you drag to the left, then the thing you are interacting with should move to the left, but in their viewer the camera rotates to the left, so the world rotates to the right, which is backwards!

It works the way you want for me. I drag left, the boat rotates left. Also, while I agree with you that this is how it should work and is the "one true way", I can tell you from working on CAD that there is a whole world of people out there that want the camera to move based on mouse movement. In their mind, moving the object is as strange as moving the camera is for me. It seems there is no "right" way, just a few different ways.

Edit: Oh it's worse. They are using turntable navigation.
