What a tremendously poor argument. NeXTSTEP never caught on and was a commercial failure. macOS is based on it. Netscape Communicator was open-sourced after it fell to Microsoft and later became Firefox. Not everything that dies deserved to. Successors are not their predecessors. BeOS provided a good base for developers to work towards, so the project wouldn't get bogged down in trying to be "something new".
