Do you think that google and other main search engines know who searched for "Byzantine" before the bitcoin genesis block?
Yes.
Would the creator of bitcoin search for: "Byzantine" without using Tor browser and/or VPN?
Probably no. I'd expect him to be extremely cautious with his privacy. Tails didn't exist in 2008, but he must have had different user in his computer for this kind of activity. For example, anything related with the "Satoshi" identity would occur there. Coding, forum posting, emails, domain name registration etc.
None of our business, though.
