From what Frogboy said on UQM, it seems to me that this was a risk-mitigation move, presumably to keep SC:O from getting injuncted. They have apparently removed the Arilou/Chenjesu DLC, removed the use of ‘Melnorme’ and ‘Arilou’ from the game, and redesigned the Earthling Cruiser to be less like the SC2 version, renaming it “Terran Cruiser”.
That said, he was clear that they weren’t conceding anything, and that the outcome depended on the trial or a future settlement.
