Why is the world starting to accept this as fact all of the sudden?
Perhaps you've heard of it already -- there happen to be some strange people in this world who are fond of the idea of "alternative facts" (which in fact are, of course, merely falsehoods/lies). Who cares much about all those Satoshi Nakamoto rumours these days anyway... whether he is Satoshi or not (most likely not), Bitcoin is Bitcoin, a network that operates on a
cryptographic protocol.
Arbitrary articles designed for clickbait such as the one you linked seem quite bland to me (just like this topic's title "As it turns out, Craig Wright actually is Satoshi!"). The article's beginning "If the gossip at a recent invite-only bitcoin conference is any indication (...)" is enough to understand what it is all about. So boring!
