- couple BScartel people back him up.
got some reference for that?
maybe I missed it but I can't recall anybody apart from Gavin Andresen to back him up.
and I did a search right now and found 2 names only: Gavin Andresen and Jon Matonis who flew to London in order to meet CW. and surprisingly (not really) Jon Matonis now has the executive position (Vice President) in the nChain firm!
COUPLE.. seems you answered your own question
however more of the BScartel were 'invited' but declined to get involved
(google can help you, as you have learned when answering your own question)
you may think gavin is not part of the BScartel due to him leaving core and going with XT/Classic in 2013-2014
yet that was just more social drama distractions to point fingers at XT/clasic while blockstream and Barry silbert(dcg) took the reaigns of core
check out DCG.io/portfolio BLOQ.. then look at who is in bloq
and to everyone else.
here is another kicker of why CW is not satoshi
CW explanation of why he chose "satoshi nakamoto"

'i have a single mother and one of the guys that helped raise me was japanese'
and then went on to waffle about some 17th century philosopher
..
but the real answer is
in 2006 the entity that created bitcoin was entertained by other game theories of decentralisation and anonymity, puzzles, cryptography and other things
there was a game which was part of perplex city. which part of it was 'finding satoshi' which had a prize.
(no the perplex city 'satoshi' in the game guy is not bitcoin inventor)
and thats where bitcoins inventor got inspired by the name and used it, much like people now have the word bitcoin as their twitter handle even if they were not around in 2009.. they just like the name of something they find interesting.
