No, my point was that no one owns it. Your logic might hold, somewhat, on the Bitcoin Core code or the latest Google Android release. Yet even Bitcoin Core could not halt Bitcoin Cash's fork. However it goes even further with the STEEM Project, in my opinion, because the Witnesses decide the final direction of the package, not Steemit, Inc.
