I'm not sure you know or understand what it is they need to learn. There are different ways to regain market share. Significantly undercutting competitors is one way to get people to buy now now now. Consistently making available to the market viable competitive products is another way without relying on heftly price undercutting, although it is slower. This requires consecutive delivery of good products, or well received products, to battle for buyer purchases quarter after quarter. Following up every good product launch with another compelling product next time, and the next, and so on.
That's where they have failed, regardless of the intermittent strong products they have released, or products that really come into their own several months later.
Its more sustainable and better then pricing themselves to bankruptcy as I take it you appear to be advocating.
