The poster alludes to George Orwell's
book "1984". The novel describes a political system in
which citizens have no basic rights.
Please, don't get me wrong - I
don't hold the view we have a totalitarian system.
However the poster is supposed to show that there is this possibilty, which can't be excluded, when the state gains more and more control over the citizens' privacy.
Noone ever knows what could be in future, consequently everyone should be aware of his rights.
