People using Google search are not customers. They are visitors to a free web site where you can type stuff into a box, and other stuff appears of that web site's choosing. There are various assurances made or implied about what that stuff consists of. Those come from the website itself, so you're foolish if you completely believe them.

How about people who use other free stuff? People who load up GNU/Linux and log in to a Bash promp --- are they "GNU customers"? Does GNU have a monopoly because the users don't bother to find out about other operating systems and believe all the evangelizing which tells them that GNU/Linux is the best?
