This is just another documentary where they are trying to identify Satoshi but they aren't and the tweet is very misleading.
Yes, seems you are correct. On the official site of the documentary (its name is "
Money Electric: The Bitcoin Mystery") the following can be read:
The documentary film offers a thrilling, globe-spanning investigation, with Hoback immersing himself with key players, uncovering never-before-seen clues, and humorously unraveling Bitcoins meteoric rise.
So it may bring some few new speculations to the table, like new findings in Satoshi's writing style (a likely element in the documentary could be an AI analysis of his forum posts and emails

), and even perhaps something another early contributor said during an interview, but the wording of this description is very close to the Newsweek article when they "identified" Dorian, who is
extremely unlikely to be Satoshi.
Edit:
If someone could sign a message proving himself and satoshi and the block Genesis miner, this would be terrible for bitcoin. Bitcoin would have a CEO, this would be the beginning of the end.
Nah, I don't think so. There is no formal power for the creator of the Bitcoin software.
Informally, if his identity is revealed, he may be an influential voice, but one among many I believe. He could in theory threaten to sell his ~1M bitcoin if the devs do something he doesn't approve. But that threat could only be dangerous in another hard fork, otherwise maybe it could mean a 20-30% dip.
