I won't disagree that Soldier's gayness came pretty much out of the blue, but I don't think it's a good example of something that was "put it in our face". I play Overwatch regularly still with people who have no idea he's gay - the game itself doesn't say anything about it, at least not that I've seen. The only way you'd know originally is if you followed Overwatch social media or read the blog post they announced it in, something that only a small fraction of players actually do.
