This reaction over the Asuna's fall is normal, expected even. The pacing was the problem everyone seems to agree with that so there's no reason to keep beating the proverbial dead horse.
Some time ago i said this " the transition from reluctant heroine to willing whore is the point where many NTR authors make or break the story" and unfortunally for several reasons (techinical issues, inexperience in long plots) Fujino had to break the narrative, but he kept his original argument intact, Asuna in his story is a hypocrate who tries to rationalize her faults and shifit the blame of any her wrong actions to someone else.
She broke after the Fake Kirito, there Fujino made the choice in the next update instead making her to be conflicted and felling guilty for being around Kirito, split them apart and focus the next 4 updates in another Fog quest, with that he lost the momentun in the IRL plot, if instead he had kept them togheter, he would had some conflict to work with IRL and make the reason for her fall less convinent than a monitor device.
Her behavior didn't change during the story, Fujino just run out of excuses for her, because he lost the pace that's all, and the need to finish the story.
And let's not forget one old plot point, she had some sexual past trauma and suffer from PTSD even that Fujino create for her, we don't know what hell happen with her, but that could explain her being so submissive closet whore and willing to acepet Inoda's manipulation.
And NTR it's a feminine cheating fetish almost all works in this genre is always from the female/heroine perspeticve, desing to generate this type of response/revolt on men, the male version of that is NTS cuck/humilliation fetish with Fujino is more open about it now, and pushing to be one of the endings.
