Sometimes ideas or concepts, take something that somebody originally had, and put your own spin on it or try to make it work a bit differently. Happens in business and work all the time. It's better than them doing nothing and it's not worth getting feelings hurt that they might do this.
I might be more receptive if they were playing someone else and still planning something. But you know if they were playing the Kings or Preds, the idea never would have been born.
It's blatant immitation predicated entirely on the fact that we already do it. It borders on mockery.
