Are you sure? Counter-thesis: The thousands of millions of multi-user
servers run a BSD and desktop clients access the multi-user BSD servers
by single-user Linux machines, as well as Windows and Apple machines.
Or an even darker counter-thesis: Windows multi-user systems and
servers rule the world, while Apple, BSD and Linux is mostly used for
single-user desktop machines, smart phones, tablets etc. ...
Are there any valid statistics available?
