         I've experimented faith in free software and the philosophy

-        from cuban State.  The cuban State controls all the
-        communication media and very few possibilities are available
-        for cubans to build up independent collaborative networks
-        using computers inside the island for sharing information
-        apart from cuban State restrictions and conditions. One of
-        these possibilities is the telepohne network the cuban State
-        provides, which has national scope.  Generally, cubans use the
-        telephone network to talk among themselves, but it is also
-        possible to use this network to transmit information that
-        cannot be communicated using the regular method of human
-        talking. It is possible to attach computers to the telephone
-        network the cuban State provides to transmit whatever
-        information a computer can produce (e.g., images, documents,
-        programs, etc.) from one location in the island to another and

-        information in a way that only the target computer is able to

         In these last years (2009-2011), the cuban State has shown

         If the vision described above about what the cuban State tries
         to mean by <quote>reaching a technological
-        independency</quote> sounds correct to you, the cuban State is
-        misunderstanding or trying to distort the real meaning of free
-        software and the philosophy behind it.  The free software is
-        built from people and dedicated to people who might be in need
-        of it, with the hope of being useful and garantee the freedom
-        of computer users paying or not a monetary price for it.  The
-        cuban State, on the other hand, introduces free software at
-        convenience because there are entire operating systems free of
-        charge which the cuban State can study and change as needed,
-        not in the sense of guaranteeing the freedom it provides to
-        people, but as a way to control what software does cubans use
-        and the way they do that.  It is another impositions cubans
-        should comply with, no matter what they think about
