Wouldn't there be a larger deviation between estimated and actual induced drag caused by incorrect assumed masses for passengers and baggage on every flight than the short term increase in drag associated with spoiler drag on one wing on the 5% of days it's gusty across the runway and you happen to be working? As Rainboe said, these things are barely effective from 250kts and below on most medium/large jets, and control always come before performance so why try to get airborne risking a pod strike with the roll due to the crosswind? As ex-rotaree pointed out, they tell you to take it easy on rotation in these conditions and move the controls as required without over doing it, perhaps it was just an unfortunate incident where a few things were stacked against the PF in this case. I'm sure if we give it long enough somebody else will be getting criticised for not using enough into wind aileron during with t/o or landing and bending the jet.
