Mistake or not, IP is a use it or lose it prospect. They may well have no choice but to issue some sort of warning, otherwise, when there is an actual threat that they need the law's protection on, they may be out of luck. I'm just armchair lawyering this, but it's my understanding that IP law is murky, and Rogue may have just missed it's step here and needed to get engaged. Who knows what happens next, for all we know it settles out of court and everything is fine, but other industries/hobbies have been really brought down by "aftermarket" companies who were able to dilute the value of IPs. This may not be the sort of case of "little fish big fish" that it initially seems to be. Better bet is to see how this plays out before deciding who's right or wrong in this case. At any rate, there is plenty of room to find justification for whatever bias one already holds, and for me that's a red flag to wait and find out more background on what's actually going on. Again keep in mind that for the last couple of decades, the defacto rules for IP in the US are "Defend it or die" and "the money wins" I'm not sure which side of that coin we are on, but when both are a PR lose, only one has even a slight margin for long term business.
