And this wasn't just one woman and a couple of teenagers, it was a group of highly skilled fighters with a small army well versed in guerilla tactics at their beck and call with an apparently undetectable super virus at their disposal. Also, when did we see Grimm giving orders to other Grimm?

This. Plus information about the Maidens is kept secret due to its reveal on a global scale would shale the foundations of Remnant's history, religion and would otherwise cause a ripple effect that could cause Salem's efforts to become even easier. The same goes for knowledge of Salem herself, it would cause panic.
