I'm more inclined to believe it's because they secretly hate their wives, and women in general, so some freak calling them in the middle of the night for "girl talk" probably makes them happy, or at least gives them some kind of disgusting satisfaction.
Remember, these are fucking tech nerds. Absolute fucking speds with no social skills who have shit luck with women, and loathe that fact despite the reason being their above-mentioned flaws, and because they see all women as cock-gobbling whores, and don't even bother to hide that. I mean, just look at Blizzard, and the company Elliot works at.
Of course harassing their wives doesn't do anything. They probably do the same thing if not worse.
