It's not what you said, but how you said it. I can understand you may wish to believe that being correct is paramount, however social grace is always the most important. It is incumbent upon everyone to treat others with the proper respect, especially when another is wrong. Feel free to correct, but do so in a non-confrontational way. As a former controls systems engineer I can attest to the fact that A) having 14 rides shutdown seems a likely failure of backup systems and B) the rides did as designed and returned to a non-energized position without risk of injury. Inside information is always cool, but remember that a large portion of how you communicate is lost when confined to the written word. You can be the victim of someone reading what you've written from a different angle and taking offense. If you demostrate grace, your motives will never be questioned.
My recommendation, and I 've been visiting this site far longer than the number of posts would indicate (primarily because I don't risk biting the hand that feeds), take this forum, in fact this entire site, as an opportunity to educate others when sharing facts or your opinion. This is my approach as a former CM and consultant to Disney Company; to behave as if I was working.
