Are DApps really decentralized?

I'm curious, are DApps, or Decentralized Applications, truly decentralized in nature? It's a topic that's been debated within the cryptocurrency and blockchain community. On one hand, proponents argue that DApps run on decentralized networks, free from central control, making them inherently decentralized. However, others raise concerns about the potential for centralization within the development, governance, and even usage of these applications. So, is the decentralization of DApps a reality, or is it more of an idealistic aspiration?
