Why, though? Couldn't Microsoft work out a deal for partial ownership of the divested entity? They would still be able to claim part of the revenue stream as their own. They could also set up an arrangement for publishing rights on Xbox platforms, which would give them full marketing rights to those versions of the game. They could also get access rights to the content in Game Pass, though maybe at a higher price for Day 1, and retain all the MTX/DLC revenue from the game on their platforms (Xbox and Game Pass). Meanwhile, if say the divestment only affected the Activision side, or even Activision & Blizzard, King would (should) be exempt from that, and hasn't Microsoft repeatedly said this deal is mainly about mobile?
