propaganda != propaganda

They block propaganda of the government agencies of a country that is currently in the middle of hostile, widely condemned by the West, military operations in another sovereign European country.

It's also likely they blocked it because then non-state approved opinions about war can circulate more easily. They already shut down those few more free media that were left so it makes sense that they would crack down on alternative platforms too.

It got banned because FB refused to stop fact-checking state media posts.

Some time you need to take sides. Perhaps if that happened in 33, 34, 35... we would not have 39.

Did they censor the pages in Russia too?

Afair, it was them censoring them in EU
