I think the Fed has merely found another avenue to move freight even cheaper for their "price point" type of customers who don't give a rats arse about things like exclusive use or if the guy shows up in a Fed branded truck. This leaves the purple and blue available for the rest of the customers who do care.
I dunno about anyone else but NLM has been a good thing as far as my dealings with the Fed, I've made a lot of money from it.
