I think many people liked Asuna's slow corruption through deception and manipulation by Inoda more, when she mentally apologized to Kirito and all the time convinced herself that it didn't mean anything. And this update caused Asuna to break down not because of corruption, but simply because of Kirito's revenge for treason. It looked like this.
I understand that this is NTR, but Asuna reacted to Kirito's betrayal as if she hadn't cheated 3-4 times in the game and 1 time in real life, as if her heart had completely broken. And it's pretty weird. It would be more logical if she reacted - "Well, I'm basically the same, and this is just a game and it doesn't mean anything to Kirito and me." And the sex at the end of the update would be because Inoda whispered to her that "he can and you can too, it's a game," and not because she was upset and offended.
This update changes quite dramatically, as if the author is in a hurry somewhere. Apparently people didn't like it.
