This really highlights part of the beauty of open source code, though. You usually have plenty of options for large well-maintained projects. If an obscure, abandoned project fits your needs better, you're free to inspect the code, modify it as you see fit, and use it.
On the other hand, when Windows 10 goes end-of-life, I have no option to fork it and use it as a custom project. I can switch to Windows 11 (zero chance of this happening), use an outdated version of Windows 10, or convert to Linux.
