That's also because they've had problems with this device in the past. If they didn't voluntarily recall the new device, can you imagine the drama that would create? AB is covering their butt. However, it's a good thing. They know what would happen if they were forced to recall.
It comes back to money. Voluntarily recalling a product looks better than being told to do it. Stocks in the company would fall and have a monetary impact on that company. Also, AB's reputation is also on the line.
So, yeah, they recalled the device. Makes perfect sense.
