The internet is not perfect and can be censored, surveilled, and controlled by a few private corporations or governments. There have been projects that have attempted to decentralize the internet that are laying the groundwork for achieving it.

An example is Starlink - a project for building decentralized satellite networks for connecting rural areas to the Internet without relying on expensive ground infrastructure or government subsidies.
