It wasn't so much the net ~$3B (piffle!) but approximately doubling headcount with the sort of people who got Moto to where it was before they were bought, and having to manage all that in a direction where a sale for $0.25 on the dollar is considered a success ($0.55 if you count the divested bits). It isn't quite as irrational as buying Nokia, but it's right up there. Moto was a big giant messy falling knife.
