I guess the question you should be asking then is why the bar failed. Ya know. Because we already know it did.
"The fuselage's structural integrity failed when it hit the ground..." could be a truthful description of why a plane is in bits after a crash... but it avoids discussing the more critical point which is.. how did we get to that point. The tow bar is not intended to fail... so it failing is a failure of operation, another component failure combined, a maintenance failure, or a process failure. Typically these systems are designed to not be a single point of failure, so there are layers that failed here. That's why people with any background in the sciences or systems aren't simply satisfied and closing the book with 'the towbar failed' answer and press on further.
