I think a better response is - what if they did have something to hide? What if they were a government or corporate whistleblower, a human rights lawyer, or a journalist? What if the government changes and suddenly their friendship with a Tibetan sympathizer becomes a liability?
What if they're none of those, but due to their carelessness, make whistleblowers stand out because they're the only ones trying to keep some privacy, making them easy to find an retaliate against?
