I guessed his name because of his employer and maybe there could be blackmail material or dirt on him that is kept hidden. Most people I know think he’s one of the few on the tube that is worth watching. So it was just a wild guess by me.
But there is an SH as one of the “unknown” founders of Google. His name is Scott Hassan, who wrote the code for the original search engine for Google. He is never talked about when discussing Alphabet.
I think the SH is for Stephen Halper
