I would not say Zuckerberg has no moral compass. He definitely has one. Hell, he started only eating meat that he personally killed. What I would say is that his moral compass points in a VERY different direction than the vast majority of society is familiar with. He's a kook, basically. His views on privacy are not that he 'doesn't care'. He made it clear early on what his viewpoint was. He sees privacy as an antiquated, outdated notion that everyone will benefit from the death of. He believes that once everything is out in the open, people will grow up and stop being judgemental about things that are statistically normal despite being in contravention of social norms. He is, of course, completely wrong on that point and gives the majority of society far too much credit. But it's wrong to say he has no opinion on the matter.
