When a company really hits hard times you expect them to be much more deliberate about how they cut, they start making decisions about which businesses do they really want to be in and how much do they want to spend. Facebook is a great example of this. You take a look at the business and say "What's the core business" it's ad-supported social media, you look at the focus and spend and it's this weird hardware platform that's a big bet and probably a long way off and not really connected to the core business. Facebook has completely lost focus on its core business. So this focus on efficiency seems just silly. A lot of these cuts seem entirely driven by some meme about the economy rather than actual real market pressure. When real headwinds start to hit, the cutting is going to be far more about focus and direction than on this vague idea of being lean. It doesn't matter how lean you are while designing a headset, because you're running a social media site.
