This particular survey finds things that are connected to the public internet. For example, the WD NASes used are specifically those NASes whose owners have chosen to connect them to the public internet. The squatters probably don't intend anything at all evil, but their address use conflicts with access to the general net. If you addresses that aren't yours and you expect to be able to connect to web sites in general, you might by chance use an address that is later allocated to a web site you'll want to use. If you squat on 193.168/16, that's 2¹⁶ addresses and you might block your own access to a few thousand web sites.
