All users on an Ubuntu system are members of one or more groups. By default, new users are added to a private group with the same name as the user (in the above example, the account created for user john was a member of a private group also named john).

Since Ubuntu version 16.04, the spyware search facility is now disabled by default. It appears that the campaign of pressure launched by this article has been partly successful. Nonetheless, offering the spyware search facility as an option is still a problem, as explained below.
