According to the developers, Rebound 11 does not modify any essential system files but offers plenty of new toys for power users to experiment with. After a “simple” installation process, the tool introduces its own WinUI apps that change several aspects of the Windows 11 experience. The package includes a couple of WordPad-style text editors, a modern file explorer, a redesigned Control Panel for managing system settings, and more.
The tool is foss, the purpose for its existence is not. What I really mean is volunteer devs spending time subsidizing a three Trillion dollar private business with free labor isn’t ideal. There’s many other projects where the time could be better spent, projects that can benefit everyone, now and in the future.
This isn’t strictly directed at devs of this tool, every month there’s a new "Fix11, “New W11”, “11 Decrapifier” tool released and everyone nods along like this is okay.
