The irony here is that both SerenityOS and Redox are UNIX-like. Of course in their design, they're not purely like most other UNIXen, but they also don't stray away too far.
They offer a POSIX like API on top, which isn't the same thing, as the key APIs, and overall system architecture, are something else.
Also mostly because as it happens in most hobby projects, people keep wanting to replicate GNU due to the existing software, thus keeping the UNIX cycle alive.
