We've done price elasticity studies, and the answer is always that we should raise prices. We don't do that, because we believe -- and we have to take this as an article of faith -- that by keeping our prices very, very low, we earn trust with customers over time, and that that actually does maximize free cash flow over the long term.
科学教会我们谦卑，因为每一次发现都揭示了我们无知之广。
沉默是上帝的语言，其他一切都是拙劣的翻译。
