Thanks for the reply. It's true that Facebook the company is an emergent entity, and that the companies behavior and "wants" don't necessarily match those of its employees. I disagree with the claim that "any technique you might use will obscure what's really happening in one way or another." RCTs that measure self-reported wellbeing and other engagement-independent measures of mental health do not obscure what's really happening. Techniques like this could be used to actively improve user health, even at a cost to engagement.
