The background of the movie takes place in Warsaw in the 80s but, according to Kieslowski, he doesn't want politics to limit what is characters are able to do.
In an interview he had about Decalogue, he said:
*"Everything is important except politics. Loneliness is important. So is love, and the lack of it. Hopelessness, everything. Politics is not, because it isn't there. It only emerges in absurd and insignificant situations. That's hardly politics, but rather the consequence of political ineptitude. There's no water, elevators don't work. The basic things of life become problems. Life is organised in a bad and stupid way."
Across all movies, each character has to deal with a problem or creates a problem not caused by the government but because of life. The government steps in after the problems have taken root (the firefighters come after Pawel falls in the water). It's a not a deep analysis but I would assume Kieslowski would say that government's attempts to inflate people's privacy is a result of the rapid changes the internet has made to society and the government's inability to control that.
Additionally, many of his beliefs and the themes in several of his movies are influenced by politics.
