It's not a secret. It's unfinished. That's the problem. It was considered a leak because it's unfinished. If it were an OS or library update, apt-get update all day. Those still have to be committed before you can update. This was a phone firmware revision that was unfinished. Nothing to do with opensource - there are updates for Maemo5 OS that once are finalized, they're committed and you can get them. But this is a firmware update for the phone... slight difference, especially when it's unfinished as it seems to be.
