Agreed, either way it looks bad but I would figure they would be all to happy to blame the FU on hackers. The only possible motive I could come up with for Go Daddy to blame an outside hack on themselves would be if the hack was THAT severe. Like major stupidity (or liability) on their part could get them sued by businesses that lost money due to this.
Of course it is also possible that they just have no clue that they were hacked.
