You never know, 99% or so of comments you see under an SAO NTR doujin or game include people saying how glad they're of seeing Kirito getting NTR-ed, like the actual Kirito would ever be as retarded or useless as most NTR plots write their male leads compared to their real selves XP Is not just making the girls complete sluts, one must remember that NTR plots of known shows always also only work because they take away all the intelligence and resources the MC has at their fingertips
(If anything, Fujino again surprisingly was 'nice' to Kirito in that way, as retarded as he made him he actually let him keep his hacking ability, is how he took down the 'lewd blog' from Part 1 just because...albeit he took away his government contacts, his actual canonical above average sexual prowess and, even if he waited until late Part 2 to clarify why, Yui, because all of them would have instantly solved the issue that is Inoda instantly XD). And he even bothered to actually clarify the authorities are corrupt or under the influence of the bad guys to solve the usual "why the retards never cap the cops" issue you see in like 70% of NTR!
Essentially, NTR plots almost always require the writer to completely make the MC be borderline an OC as otherwise they wouldn't work, unless it's one of the REALLY pathetic MCs that are completely useless canonically without their girls and have no real power or competences.
