What is snowball blamed for?

In George Orwell's "Animal Farm," Snowball is blamed for various problems on the farm, particularly the destruction caused by humans and failures in agricultural production. After he is ousted by Napoleon, the other animals are led to believe that Snowball is secretly sabotaging their efforts and collaborating with their enemies. This scapegoating serves to consolidate Napoleon's power and divert attention from the farm's real issues, reinforcing the theme of Propaganda and manipulation.
