The arms race continues.
When someone comes up with a new defense (in any field: sports, computers, law enforcement, military), WHY do they feel compelled to tell the enemy how it works? Sure, they might eventually figure it out on their own, but why help them? My advice would be STFU.
It's like a stupid baseball manager who says they always hit a certain pitcher because he holds his glove differently when he is going to throw a curve. So the pitcher says, "Hey, thanks!"
