This "rule" against passive voice doesn't exist in every language.
What looks like good writing in English may look like childish, repetitive prose in other languages.
The "rule" doesn't exist in English either.
Most of the people complaining about the passive have either serious trouble identifying a passive at all, or can't construct an argument why it's bad to save their lives, as amply demonstrated by Geoffrey Pullum. http://www.lel.ed.ac.uk/~gpullum/passive_loathing.pdf Section 2 is a bit technical, but the rest is a great read.
Tolstoy's War and Peace would frustrate you to insanity in that case.
