The long-awaited launch of EOS’ mainnet has been further delayed after a BP vote held on June 6th failed to give the green light. A new vote is scheduled to take place 24 hours after security firms perform an audit. At that time, if BPs do not identify any further vulnerabilities the launching process should take place.

So yes, they were wrong about how much they knew they control. I guess the delay is good for the platform overall. Better to solve a dispute before it becomes a huge problem.
