It's yet another fake.
Anyone can create a key with any name or email address they want on it.
Someone created a key here, they typed "
[email protected]". It is not Satoshi's key, the name and email address are just entered by the user and not validated.
Then they signed a message that says "I created Bitcoin, I am Satoshi Nakamoto - Craig Wright" -- that's what the BEGIN PGP MESSAGE part decodes to.
Because they're incompetent with PGP or trying to be intentionally confusing they didn't use the clearsign option, so you have to decode the message to see the text being signed which is probably contributing to confusion. People think you need a key to decrypt it, you don't.
I'll do the same-- it only takes a moment (except I'll use the name Fakamoto). You can decode the message by running gpg -d and feeding in the "BEGIN PGP MESSAGE" block.
