At this point, it would be better for all those involved [1] if the corporate entity called Activision-Blizzard was burnt to the ground and a new games company was built in its stead, with actually competent managers [2], a unionized labor force and actually enforced zero-tolerance policies on abuse of all kinds among some other nice-to-haves.
[1]: Obviously not Kotick and the rest of the scum, who not only tolerated but even engaged in the "alleged" instances of all manners of abuse for years. I actually wouldn't mind if they provided themselves as kindling on that corporate bonfire after having their golden parachutes cut away to pay damages/"reparations" to their victims.
[2]: ie. with at least a background in games development, not how to best financially screw their workers.
