These measures definitely hit many users that aren't causally responsible for the acts of their government. Some may even be in open opposition of the acts committed in their name. Unfortunately, the latter is but a small fraction of the population. The vast majority of Russians are remaining silent. The chance that these blocks will prevent any of that group from learning about the war when they still have not been reached at this point is slim. Blocking of accounts doesn't usually prevent you from reading the news, anyway. Russian media is downplaying the event. Making peoples' lives inconvenient has the chance of making them take notice, which is a first step.
