In what way is privacy anti-corruption? My point was that having better privacy makes corruption easier, which is why saying the Singaporean government is taking aim at corruption undermines your argument. If you can untraceably accept payment for a deal that was set up and negotiated without the possibility of eavesdropping, you've got the perfect tools for corruption.
Good point. To answer you directly---in short they like whistleblowing.
More long-form they like some of the protection features---e.g., protection against corporate espionage from China/USA. They probably also like to use such technologies to spy on their neighbors in efforts to leverage that information to negotiate better trade deals.
