The difference isn't that many more are supporting Russia. The difference is that many more don't have clear-cut sympathy for any side.

I personally are much more sympathetic to Ukraine on different principles than most, but I definitely understand why many are not willing to trust the main media line on this. We went from hearing about how Ukraine was a deeply corrupt country, barely a democracy, to immediately hearing about how they are only being attacked because of how democratic and amazing it is and that Putin is scared Russians will want to live like Ukrainians. Media started glossing over Nazi imagery on the very pictures of soldiers they spread, not even mentioning it. There were many more narrative flips that I won't get into as a matter of time.

Because of this, people that are less informed or that have a more traditional understanding of the morality of conflict will naturally get skeptical and decide that they don't want to sympathize with anyone.
