I think the biggest reason Zuck is so lifeless is that his honest opinions are extremely polarizing. When your market segment is "everyone on the planet", anything you do other than the most bland, boring things, will alienate some part of your potential user base. Combine that with Zuck's general "Users are pretty fucking dumb" attitude early on, and I bet not only are his real opinions polarizing, they're also probably pretty damn misanthropic. Hard to sell a product to "everyone" when you come out as generally anti-"everyone". If there is still even a "real" Zuck left under there, I bet he's completely unlike what we see in the public eye. Not exactly a huge revelation, but people forget sometimes the dynamics at play when Zuck decides to say something, and what FB stock will do as a result.
