Yes. It shouldn't have even been in the running, ergo any decision on it is unfair.
See how annoying it is when people decide that their opinion of a game trumps yours? Now imagine being a reviewer, or a judge on the game awards, and the reaction, the scrutinising (That Twitter post is what's known as a joke. It's non-literal hyperbole. It's a common part of English verbiage, and has analogues in most languages), and the complaining that they're mistaken, because you think differently. God forbid you ever like something which is truly outside the mainstream, otherwise you'll have to deal with it all the damn time (Playing videogames doesn't count, especially when you wrap yourself in the safety blanket of nerd culture).
What we have here is called "Anomaly Hunting" and it's conspiracy theory thinking used to justify presupposed conclusions. What this really says is that he knows about Bayonetta 2, and he has an opinion of it, and that opinion is that it is probably not deserving of the winning title. WHICH IS EXACTLY HIS JOB AS A JUDGE. TO KNOW ABOUT THE GAMES AND HAVE OPINIONS ON THEM. Really, the only improper behaviour here, is that he kind of spoiled the show.
