So a quick strawpoll for you all. Just something I have been wondering. Would you consider a diff to be “open” if it acted like one (example, one wheel in the air spinning freely) or do you define it purely by its mechanical limitations (example - an open diff is one that only allows for no torque to be sent from one axle side to the other under any circumstances.)

A converse way to think of it would be brake based traction system. if the differential isn’t mechanically locking but the brakes provide a locking effect, is that a type of LSD or is it just a simulation of one.

I know this seems stupid and thats only because it is. Thank you for your time.
