I live in Hong Kong and...
...the press has gone batso with this case since it broke last year. Here's a couple of notes:
- Edison Chen was an extremely popular young star until the photos were leaked.
- Although Hong Kong movies have become world-famous in recent years, it's still a highly conservative culture. Unlike UK/Europe or even Hollywood, top HK actresses do not do topless or nude scenes, as it usually stops their career (yes, I know Shu Qi is the exception, emphasis on "the").
- According to today's local newspaper, the South China Morning Post, the tech "unlocked the encrypted files" on Chen's laptop, which, BTW, was a customized pink MacBook, seriously.
I have no special inside knowledge, all of this info has been published or is generally known, but outside of Hong Kong, it may not be well disseminated.
My personal opinion: young people all over the world take these types of photos, they were intended to be private, and their de-encryption/dissemination has caused great pain to the parties involved, especially the women. Both Gillian Chung and Cecilia Cheung appeared on television earlier this year and expressed extreme anger at having their private images (pun intended) splashed all over the Net. This isn't a Paris Hilton sort of thing, where leaked naughtiness leads to pointless fame, rather, the reverse: the equivalent of a logic bomb with your name on it dropped into the network you admin. Multiple careers were destroyed, Chen's received death-threats, and the whole incident is less fun than may appear at first glance.
