"Always" my ass, Al. They've used special guest refs many times, but far from "always" and far from using this same tactic. Don't be hyperbolic/ridiculous. Speculate all you want on why WWE may be doing this, but don't act like this is the norm or something. It isn't, and what people would do or say if the special guest ref were someone else is irrelevant. It's just a pointless, condescending comment to make it seem as if people have no right to be upset with this turn of events.
Triple H is the problem. Just 2 years ago he officiated the SummerSlam main event. The finish of that match was an overbooked debacle, and the resultant fallout was a feud between him and the hot guy with Triple H going over. Just because WWE treats people like they have the memories of goldfish (and clearly, as demonstrated on this forum daily, many do) doesn't mean that everyone has forgotten what happened under this exact same stipulation 2 years ago.
Triple H's presence will be an unnecessary distraction. Trips and Vince have latched onto a hot Superstar and angle in order to get their shitty angle over. And no one has to like it, especially when they've been given good reason to expect this to negatively impact a highly anticipated match.
If you're going to knock people for "whining" come with something better than hypotheticals and hyperbole. This is a justifiable concern by people who have been watching wrestling long enough to know that this isn't what "always" happens and are smart enough to know that
