Less chances to overlap with the RFC1918 address in a home network ? (a silent assumption here is that the CPEs are user-configurable in any way).
Or just that they had historically some 10/8 space already used elsewhere in the network ?
Note that they're not the only ones camping on DoD address space, I know a couple more folks who had to do it out of necessity at some point, under the assumption (flawed, sure) that DoD probably will never advertise them.
The best way to solve it is to go IPv6-only in management, and for those folks who are lucky enough to have had public IPv4 space for management purposes, that is one of the big drivers.
