We live in a Wikipedia world, where file-sharing and blurry notions of personal privacy have, for some young people, made the idea of proprietaryknowledge seem like a foreign, almost ridiculous, concept.
My co-workers did not seem to mind using this information, because so many had spent significant time at these different firms that to them it was public knowledge and not viewed as proprietary information.
But, as soon as the use of the software crosses from shared application infrastructure to proprietary advantage, OpenGamma must someone agree not to share that knowledge.
