alt Hacker NewsThat's the weak evidence. Nobody cares that they both like open source and freedom, half the cypherpunks list fits that.
The parts worth engaging with: Back described a system combining Hashcash and b-money with inflation adjustment and public timestamping on the cypherpunks list between 1997-1999. That's basically Bitcoin's architecture, a decade early. He was one of the most prolific digital cash posters for years, went silent when Satoshi appeared, came back when Satoshi left. And this person who independently arrived at the same technical design also independently landed on the same Napster vs Gnutella analogy, the same celebrity email filtering idea, and the same FDR gold ban trivia.
Any one of these is a coincidence. At some point you have to ask how many you need before the simpler explanation wins.

I agree with the parts worth engaging with. I hate when people weak-man arguments.
But interesting as this is, there are others who fit at least as well. That bit gold was the closest proposed scheme to Bitcoin is well known, and we know the proposer of bit gold (Szabo) was actively soliciting partners to help implement it as a real system right before Bitcoin appeared.
Also, people leave mailing lists and come back randomly months later all the time. Adam could have simply been unlucky, and busy with other projects at the time of the launch. Lots of people were, and kicked themselves for it (which honestly, it seems Adam did too!).
Adam Back is credited in the Bitcoin whitepaper as the inventor of Hashcash. W. Dai is credited as the inventor of b-money. But Nick Szabo is not credited as the inventor of bit gold, by far the most mature of these ideas floating around at the cipherpunks mailing list at the time. That's a conspicuous absence.
All of those similarities can be explained by Satoshi having read what Back wrote.
This article is a great example of "strong + weak = weak".
I only made it to the interesting stuff because of Carreyou's name, otherwise I would have stopped.
The email timing and lack of email metadata were also strong, in my opinion. But all of this nonsense like "Wow, these guys both talk about PGP??" distracts from it.
It's been extremely widely known that whoever created Bitcoin had a strong interest in Hashcash, and perhaps created that or worked on it, for years and years. If that's the only smoking gun, why didn't we identify Satoshi long ago?
I remember having conversations with my brother about Hashcash at the time. There were plenty of nerds that followed that mailing list that had similar technical and political ideas, so I think you'd find a high number of coincidences within an audience that I'd guess was a small multiple of the number of people active on the cypherpunks list. There definitely were a lot of people at my brother's college discussing the same ideas.
FWIW my brother did his own bit of Satoshi hunting with coworkers at his hedge fund. They didn't come to a strong answer but my brother believed Nick Szabo was probably part of a group that helped edit the paper. He suspected Hal Finney was involved similarly at a minimum.
