Yeah and if you look at there numbers, they can just afford it. When you realize how big zuckerberg still is.
How is it a bad thing if a company goes all in on burning cash but at the time have never reported a net loss quarter since its IPO? Its their money to burn at this point who cares
If you scroll Instagram for a few minutes you'll see what they have been working on and that are also making a ridiculous amount of cash by selling and serving ads while burning some on side projects like that.
