Re: A choice of Evils?
It's obvious why this specific contract is sole-source.
It's to provide a leading-edge cloud service, not develop technology or standards, or figure out what is the lowest-common-denominator service.
If they had multiple suppliers, there would have to be compatibility. That means any one of the winners could halt cloud deployments until they had something compatible and working. A technology-trailing contract winner could effective make the service pointless. Sure, they wouldn't make money, but if your goal is preserving your very profitable legacy services through other contracts, undermining this contract would be an easy call.
