This was a fun article, but also an oddball collection of strong and weak claims.
Some of the "isn't it interesting ..." type coincidences would, as people on this forum would know, be commonplace among the subculture or even just technologists, and often lack the comparison to the overall Cypherpunk corpus - for example: no, studying public-key cryptography in grad school certainly isn't a high-signal differentiating tell for Satoshi-ness.
For some he does provide that though, and they're certainly compelling.
What I like best about the Back attribution is that it totally makes sense in context of my operating model of humans and passes the Occam's Razor test: Still actively involved, interested in the governance, interested in acclaim/prestige, built up wealth masking his other wealth, etc. Ego and "Tell me you're Satoshi without telling me you're Satoshi" written all over it.
Interesting: my Occam's Razor test is "$100B sitting around untouched, how can that be?" Well, simplest answer is that satoshi is dead.
