DMO and "The Little Guys"

Maybe someone out there can help me get a grasp on all of this. From page 10 of the report below. A quote from DMO Commercial Manager, Harry Dunstall.

Mr Dunstall: The little guys. There is the big Commonwealth and 'if you want to do deals with the Commonwealth you basically accept our terms and conditions or you do not do business'

It seems there are lots of law firms to help out the big guys but I don't know if that ends in doing the right thing. How hard is all this if you are an SME? Is the government being fair to home defence industry?
