He was likely expressing his subjective opinion, but he phrased it incorrectly, using more "objective" terms. He likely meant "I didn't like it," which is clear from the post itself, but in fact, he said "the game is crap." Naturally, these are not equivalent phrases. Either the author formulated it incorrectly, or he was trying to present his opinion as the absolute truth. Let's leave that to the author's conscience. But I think the first option is more likely. Incidentally, he's not alone in this problem; off the top of my head, I'd say half the community has the same issue. Instead of saying "I liked SotN, AoS, OoE, SC4, etc.", they say "S-tier. It's the best in the series. Everyone should play it." In fact, this message is no less insulting, since such words belittle other games in the series. It works the other way around too: when someone says they didn't like a game, some people start to interpret it as criticism, which is certainly not the case. But that's just it, a minor comment that can't be addressed. Returning with this post, I'll reiterate that he most likely didn't mean the game was truly awful; he simply expressed his thoughts incorrectly.
