A lot of the companies that have class A networks had them issued before CIDR. Also don't underestimate the size of some of these networks. Ford has a half dozen datacenters spread out around the world thousands of VOIP phones, Desktops / Laptops, routers, switches, AP, servers. Not to mention most modern manufacturing plants PLC's run on a IP network sure you will never use the whole space but do you really think they are going to re-IP a network that size. Ford also owns a class B network :)
