You should be better able to judge your management and their inclinations than HN folks who don't even know which company you are talking about. "one of the only people" implies that you are not alone with the extensive knowledge. If they fired you could they still continue? Are the management even smart enough to know how much they don't know? or how vulnerable they are? I have had many bad experiences with managers who could consider your demands for a raise as a form of ransom. Consider @jerryu's suggestion.
