I heard that the recently pirated Haruhi movie, in which I have no interest otherwise, made it clear fairly explicitly that Kyon actually likes all the bullshit (and apparently wants it back when it stops or something like that). He's still a battered husband, but a voluntary one, like the majority of them.

Keeping it in mind, I rewatched the original DVDs (6 episodes, of course). I have to say, the official story is just fine. But it was a nice bonus that the presentation was ambiguous, especially if you like to play with your dolls, even virtually.
