You've got to bear in mind that this is domains moved off GoDaddy's nameservers, and I imagine a large percentage of transfered domains would already have non-godaddy nameservers.
I know that for the 40 or so domains I transferred off of Godaddy none of them used Godaddy's nameservers. Indeed it's ill advised to use your registrars nameservers.
I would encourage you to take this analysis down less it get picked up by conventional media.
