Mil-spec standards are the bare minimum requirements for a component to survive in a given enviroment. They shouldn't be used as a basis for design but are often done so to save money. That's why programs are required to define Key Performance Parameters (KPPs) for the system or component to achieve. Often you will not achieve the minimum threshold performance defined by the KPPs by just following the Mil-spec standards. Extensive test and evaluation confirms this.
"Lowest bidder" refers to the contractor that builds the system or device fulfilling most or all the customer requirements for the least amount of money compared to the the competition. A contractor can easily be the lowest bidder by cutting quality of the work and components. The contractor will still have to meet mil-spec standards and often barely do. The government is required by law to choose the lowest bidder depending on the requirements they can meet. This is often a reason why programs go over budget or over schedule as components fail during testing which sometimes leads to redesigns of the system.
For MSI this is just back-up for their marketing and doesn't actually verify their hardware as being of high quality.
