Zuckerberg and a lot of tech/SM CEOs have a strong "rules for thee, not for me" vibe when it comes to personal privacy. One day they'll claim "privacy is outdated" or "a matter of context" in relation to their business, and the next they'll spend fortunes to protect and insist on personal privacy for their family and themselves. One can only imagine that billions they make do a lot to paper over the ethical void at the heart of many of the businesses under their control.
