How are the animals in Animal farm not used their owner having control over them?

In the first chapter of the book Animal Farm, all the animals are in the barn having a meeting, talking about how to oversee their owner. But what I don't get is how can they not be used to him having power over them. At first, I can understand them trying to rebel, but after while it just doesn't make since to me. Yeah, I still rebel against my mom, but only on certain things. Only the things that I really want to do or things that my siblings got to do but my mom is changing the rules for me. So, I can partially understand where they are coming from. Think of someone that has power over you, maybe your parents, a judge or who ever, did you eventully accept the fact that they have power over you? I don't know about you, but I would just sit back and let them take control, like they always have.
