The NSA 'owns' at least one semiconductor fab[1] in Texas, and used to (or still does) own another secure CMOS facility in Santa Clara [2]. Add in several facilities owned by defense contractors as well as the facilities at places such as Lincoln Lab. When you have the ability to develop and build your own secure technology, it would seem perfectly 'logical' to force others to use lesser, less secure hardware.
