The true owner remains an enigma. But then from the source below, there are doubts that it's from Satoshi himself since there were tweets about BCH and from Bitcoin.com itself.
News.Bitcoin.com can confirm that no one at Bitcoin.com is in control of the account or exerting influence over it. As far as can be determined, the operator of the account is the same individual who has ran it since day one. In a DM shared by “Satoshi Nakamoto”, one of the few accounts @Bitcoin follows, @Bitcoin joked about their identity, writing “I wonder who I am every day. Far too many people take fun on twitter too seriously”.
Wonder when @Bitcoin started following the account, “Satoshi Nakamoto” on Twitter, and whether the account (“Satoshi Nakamoto”) was hacked.
Well, the DM not a good enough proof that the account wasn't taken over by someone or something. Or maybe the real owner actually supported the other crypto (for whatever reason) but later changed his/her mind.
