I don't think anyone thinks the executives are unaware of what happened. OP was commenting on the optics of how Boeing is handling the situation. What I wish the public was discussing is accountability for their negligence, and a solution to avoid similar process failures in the future (and likely jail time for those responsible).
One could make the argument that the execs didn't know until after the first crash. But they definitely knew by the time the second one crashed. They had months to do something and did nothing.
There are few ways of dealing with the situation worse than the one chosen by Boeing, but late night tweets about "unscheduled meteoric burial" would be one of them.
They "own it" but they've "done nothing wrong."
