How will laws help against the same thing, but made by unlawful people? I think it's better to accept that privacy in the classic sense is dead and adjust.
Well, you can doubt it, but it is what it is: "efektivní" in Czech means both effective ("successful in producing a desired or intended result") and efficient ("working or operating quickly and effectively in an organized way") combined. Also it seems like that "efficient" in English includes "effective" as well, so there probably was no actual problem with my original comment.
Maybe it is you who should check the thesaurus and get a little more understanding of the world before posting dismissive comments.
