Yes, it did.
If Illidan had suddenly been trying to save his husband Darion Morgraine in Val’Sharah, then a bunch of people might complain because that relationship makes no sense, and was clearly done to use a political position to sell the game.
If they were two brand new characters (or characters who relationship status is undetermined), and whose story is organic to the setting? Say, two Dryads, or two male druids? I doubt it would have been much of an issue. Sure, some people would have complained, but it wouldn’t be the majority, or issue that people are assuming it would be.
And that’s the deal.
People who say “let’s have more LGBT stuff in the game” assume everyone who says “let’s not” somehow dislike LGBT people; in reality, they dislike game companies using politics to sell underwhelming games, and breaking established intellectual property to do so.
So again…
