In the "Railroaded" series of videos, it's implied that bitcointalk.org was at one time owned by Mark Karpelès. This is wrong. Mark provided free
hosting for bitcointalk.org from 2011 to 2013, which I announced publicly:
Change of hosting
Mark Karpeles is now hosting the forum's server. The forum is still owned by Sirius, as it has always been. There will be no policy changes.
I'm going to move the forum to a much faster server within the next few days. [...]
The old server was provided by MtGox. Thanks to them for supporting the forum for so long!
The new server is provided by
Private Internet Access, a Bitcoin-accepting VPN service. Thanks!
Mark never had any ownership or control over bitcointalk.org's operation.
