Your question, “What features does the Windows version of Calibre have that the Linux version not have?” cannot be answered without accepting an unargued premise: that the windows version has more features than the Linux version.

Nope, it simply asks (or even expresses genuine curiosity) about a subset of features on windows which might be missing in Linux version. That's if you want to be super logical and fussy about things. If not, you could have just answered or moved the discussion in any relevant direction you would like. That was always allowed.

Ironically, you kinda did answer it, at least in part, by mentioning the AI slop bloat. Why hide your answer behind a wall of being a jerk, though? I can only speculate. Too little sleep, too many old Rationality Rules videos? :-) Thatt's none of my business; I just hope you feel better now.
