Were they getting some sort of kickback or something?
I am not sure about Aflac but I do know there was a so call "chief IT architect" who couldn't buy enough M$ licenses and vowed to "put that god damn mainframe on the curb". He said it in every meeting he was in. He wanted server farms of M$ clusters to run the business. ALL of us called him out on it on the regular of how that wouldn't work. He lasted 5 years.
