if asicminer is succeed, the bitcoiners around the whole world will get cheaper asic rigs. It's the best way to secure the bitcoin network rather than rely on BFL alone. I think that's what you mean "by the people".
As I understand from what they wrote, their plan is to use your finances from buying shares to create ASIC, then mine on it themselves, once the difficulty goes up to a point that selling ASIC hardware is more profitable than mining on it, then they will start selling it.
