Considering the shortage of IP addresses under IPv4, I can only think of good reasons for ISPs using private network addresses. Also, not being accessible from the Internet can actually be a very good thing for ISPs, as many of these addresses are routers which need to be secure and have a minimal level of outside traffic.
