The control was transferred to
theymos around 2010 and he is the only owner and running the Bitcointalk effectively.
It's surprising how well-documented history can become totally forgotten... Satoshi created the forum on Nov 22, 2009, and was head administrator until almost 2011. Then Sirius was head administrator until
2012, which is when I took over.
Cobra also owns the bitcointalk.org domain name. I consider the forum to be basically owned by or at least dedicated to the Bitcoin community, though; I don't call anyone an owner of the forum.
That wiki article is kind of terrible...
