It has to do with how they handle errors.
When reaching certain conditions the one wheel just stops working and launches the rider. The recall is to (on most models) add a warning to the rider when they enter those conditions and generally handle it better. It's a firmware update.
Presumably the others have been handling these conditions better, because they don't have similar numbers of accidents, crashes, and deaths.
The biggest thing that stuck out in my mind was there was several deadly accidents and some of those were with folks who were wearing helmets.

I have owned some of similar monocycles and they all at least emitted a sound and had options in settings to prevent you from using full power of the motor for horizontal motion (it basically kicks you back gently once you reach the treshold and that makes you feel like you're about to fall and you lean to the opposite side way before one reaches close to 100% power).
