don't you think the guy who created bitcoin didn't know how to hide himself, he was definitely using TOR or VPN to hide his location and identity.
7 years back ? I highly doubt he was protecting his IP back then when bitcoin was just an idea, noone was.
Satoshi holds an incredible amount of BTC (UNSPENT). My theory is that he never thought it would get so valuable and moved to a different comp abandoning his older computer with the Wallet on it. If you trace the genesis Block and then continue on you will see they are unspent and still remain on those addresses.
I think Satoshi is kicking himself in the ass in hindsight
If he was just a supporter, then it would be possible, but for someone to abandon clearly a life project, i highly doubt it.
Would sooner thought he doesn't want for it to seam like creator is cashing out, and he's protecting bitcoin reputation.
