This is corporate overreach. They're suing a little guy to set a precedent. But this is the first time that I recall in the tech world a trademark holder is trying to extend their reach to a common nickname. JS could stand for many things.

Yes, the precedent that they actively defend their trademark.
If they don’t and someone challenges it they will most likely lose it and then it’s out with the Kleenex.
