There's a couple things to keep in mind here. First is that the basic concept here isn't new. We've had towed decoys of some sort or another in use since the 1990s. Second is that there's very little here in the way of details, and you'd need to know a lot of specifics to be able to counter this sort of technology. Finally, there are actual advantages to letting information like this get out, as it can act as a deterrent. With technology like this, there's some calculus you have to do about the risks and rewards, taking into account the odds of an adversary copying or countering it, the value of it as a deterrent, the expense/difficulty of keeping it secret, etc.
