The removal of Koj's name from MGS 5 was the first tip off for whatever's happening with Hideo Kojima and Konami right now. Turns out Konami is also removing his name from games retroactively.
The top image is the current MGS page over at Konami. Below it is a Wayback Machine snapshot from November 29th. As you can see, not only has Kojima's name been removed from The Phantom Pain, it's also been taken off Ground Zeroes. They've even taken it off the Metal Gear Solid: The Legacy Collection, a compilation that contains more or less every Metal Gear game ever made.
