It is better to buy than compete. (from a 2008 email) - Mark Zuckerberg

If you want to build a service which is not just serving rich people, then you need to have something that people can afford. ... At Facebook, we are squarely in the camp of the companies that work hard to charge you less ... I think it's important that we don't all get Stockholm syndrome and let the companies that work hard to charge you more convince you that they actually care more about you.

The question I ask myself like almost every day is, 'Am I doing the most important thing I could be doing?' ... Unless I feel like I'm working on the most important problem that I can help with, then I'm not going to feel good about how I'm spending my time.

Connectivity just can’t be a privilege for people in the richest countries. We believe that connecting everyone in the world is one of the great challenges of our generation. And that’s why we are happy to play whatever small part in that that we can.
