I’ve been watching the YouTube channel 1420 where they interview people on the streets of Moscow. Many of them are held hostage too. You can tell that they don’t want to speak freely for fear of criminal punishment. One guy even said something to the effect of, “Why don’t 100 Americans come over here and protest the war to see what happens.” The Russian government quells any form of rebellious organization. To take Putin out of power, it’s gonna have to come from the top or a sporadic mass protest after a Bloody Sunday a la 1917 Russian Revolution.
Not OP, but possibly the Kent State massacre was the watershed event that shifted US public opinion about the war.
