Is the command line the only way to free software?

[Jerry Feldman]

Digital not only used X on its Ultrix and later Unix systems, it also
used X on VMS. Much of the contributory work was done by people at
Digital. I worked at Cadmus computer in the mid-80s, when we developed
our own windowing system based on the Apple Mac, which the company
actually sold to Apple.

One of the real beauties of X is that it is not tightly bound to the OS.
Unix and Linux work perfectly fine without a GUI.
