My interpretation is that the reason he was relieved of command is because he used an unsecure method of reporting a situation, not because he reported it. The implications are huge IMO. First, it allowed (maybe even facillitated) a leak of sensitive information which when published, could only cause alarm to the sailor's families when there was no decision on a response. Second, the leak did something that ought to be unforgiveable - divulging the state of readiness of a important defense asset. I'm no war strategist but that's what seems most important to me. You'll have to forgive any ignorance that I might have about how things ought to work for the US armed forces because I'm not a citizen either, but it seems he had the opportunity to make his concerns known in a more secure manner without revealing information to the enemy.
