Business passengers aren't out here paying for their own tickets. Their employers are paying for those tickets, so the question is whether or not companies care about the time their salaried employees spend in the air, when those employees can be just as productive on the business-class wifi.
Assuming they're even micro-managing employee productivity to the degree that they really care about working on a plane. Personally, I never purchased plane wi-fi even when I could have expensed it.
