I sort of agree with you, but I don't think the judgment by westerners is justified considering how few westerners have contributed in any significant way toward the freedoms we enjoy and how many actively seek to undermine them (campaigns against free speech, due process, egalitarianism/"colorblindness", unfavorable election results, etc). While it's true that Russians are in the best position to fix their government, those who protest or otherwise resist demonstrate a braveness well in excess of anything most living westerners can claim, and I think that should be the posture with which we discuss Russians resisting their government.
EDIT: as a sibling commenter points out, many western countries are still directly financing the war via payments to Russian state fossil fuel companies. How many westerners would be willing to endure a year or more of high prices and economic downturn to resist the Russian invasion (yes, Americans favor boycotting Russian oil now, but (1) will they still after a year of high gas prices and (2) many other western countries are far more dependent on Russian oil than America)?
This is not entirely accurate. European countries pay billions of dollars for gas directly to the state. If they stopped immediately, the damage would be far greater than anything coming from the ordinary citizens.
