John Carmack on Microsoft's id Software Ownership

John Carmack tweets a response to the news that Microsoft is buying ZeniMax. The deal includes id Software. Since the former id technical director left the company when it was decided he couldn't work on their games while developing VR for Oculus, he now expresses hope that this will help him reconnect with titles he helped originate, like Doom and Quake:
Great! I think Microsoft has been a good parent company for gaming IPs, and they don’t have a grudge against me, so maybe I will be able to re engage with some of my old titles.
