"We have lobbied and will continue to lobby for first-party console manufacturers to either disallow mouse and keyboard and input conversion devices or openly and easily support mouse and keyboard for all players," he continued. "I encourage you to reach out to the hardware manufacturers and express your concerns (but please do so in a productive and respectful way)."
Now using keyboard and mouse is considered cheating. Sad new times.
