I wish people would actually read RFC 1918.

     Category 1: hosts that do not require access to hosts in other
                 enterprises or the Internet at large; hosts within
                 this category may use IP addresses that are
                 unambiguous within an enterprise, but may be
                 ambiguous between enterprises.

     Category 2: hosts that need access to a limited set of outside
                 services (e.g., E-mail, FTP, netnews, remote login)
                 which can be handled by mediating gateways (e.g.,
                 application layer gateways). For many hosts in this
                 category an unrestricted external access (provided
                 via IP connectivity) may be unnecessary and even
                 undesirable for privacy/security reasons. Just like
                 hosts within the first category, such hosts may use
                 IP addresses that are unambiguous within an
                 enterprise, but may be ambiguous between
                 enterprises.

     Category 3: hosts that need network layer access outside the
                 enterprise (provided via IP connectivity); hosts in
                 the last category require IP addresses that are
                 globally unambiguous.

RFC 1918 addresses for machines that fall in Categories 1 and 2.

You're assuming there that people followed the directions.

That is demonstrably false.

It's easy to say "Well, foo on them", but for those of us who provide
services or consulting to those who failed to follow the directions,
we still have to deal with it.
