I'm a huge supporter of wikileaks, but I am not a supporter of invasion of personal privacy. My thoughts and efforts are my own, and I should choose whether or not I want to share them. No one else should choose for me. I would rather have a world where I didn't know for sure that everyone was telling the truth, then a world where I lose my ability to have my own privacy.
That said, those who enforce and create law (the government) should show transparency and wikileaks is a fantastic step in that direction.
How do you lose your privacy? You have none outside the home already, and the "lifeblogging" records are private.
Let's take for an example this:
You own a gun. Without your knowledge, your child took it out of the house to show friends, and it was stolen, and he was afraid to tell you it was missing. At 3 am the Cops show up and arrest you, as the owner of the gun, for a murder, after finding your gun, with your dna and your prints on it (your kid was wearing gloves that day because it was cold)
You were alone, at home, watching pron on tv. You have no alibi, and the victim just by chance happens to be your worst enemy. You had no idea the gun was even missing, but there you are, a suspect with almost every clue condemning you.
Now suppose you have a lifeblogging VR phone, and you were using it to have VR sex instead. The SOLE part of all the data that was recorded that you need is the GPS location data that will verify that YOU WERE HOME AT THE TIME OF THE MURDER, and the case falls apart. Exactly WHAT you were doing is not need to know info for the police, just your location, in a concrete, verifiable record that cannot be disputed. You might be able to "alter" your personal record, but you would not have access to the VR carrier's computers, which would verify your GPS location, again without revealing what you were doing.
You still have privacy. What you DO NOT HAVE is secrecy.
