This is not a situation where "Ignorantia juris non excusat" applies.

I'm trying to follow but how could one possibly know information (the embargo) that has not been shared?

For the law, you can say that the law has been published and is at least available for review.

		that's my point. Someone cannot come at you saying you were still under the rules of the embargo if you had no idea the embargo existed so now you're in violation and get to suffer the consequences. You cannot say that about the law.
