What has changed in the plans for the windmill animal farm?

In "Animal Farm," the original plans for the windmill undergo significant changes as the story progresses. Initially, the windmill is a symbol of hope and progress, intended to improve the animals' lives and productivity. However, after the pigs take control, the plans shift to serve their own interests, resulting in the windmill being built under harsh conditions and with little benefit to the other animals. Ultimately, the project becomes a tool for manipulation and exploitation rather than the communal goal it was originally intended to be.
