"...  literally bug-compatible ..."

When I used to work for the phone company.... wait, I mean Bell Labs ... I
was in a department (under Rudd Canaday!) that was building an application
to print phone books, so I got to learn a little about that side of the
business. The Bells would deliberately put in bogus listings to see if the
non-Bell phone books were stealing their data. (In the one case I was told
about, they were not. The Bell company had no idea how they were getting
the data.)
