Are you saying DI's contracts with the banks lacked Non-Disclosure clauses? Or are you saying the banks hired it to engage in a phony controversy? Did the banks forget to control the data DI captured, or did the banks hire DI to publish precisely the data and disputable conclusions which it did? > Don't be so quick to discount how seriously banks take security problems > - if the losses go above a certain threshold, they get serious fast. I was neither quick nor slow to discount the banks' seriousness. I said we should assume they cover their own needs, not ours.

I do not know anybody who disputes that banks take security seriously. I do not think anybody should dispute that banks conduct cost/benefit analyses... especially not the banks themselves. Nor should anybody believe "customer" is a synonym for "owner".
