Based on the account name, bio, and internal evidence you should assume this is Don Hopkins. His Wikipedia entry at https://en.wikipedia.org/wiki/Don_Hopkins includes:
> He inspired Richard Stallman, who described him as a "very imaginative fellow", to use the term copyleft. ... He ported the SimCity computer game to several versions of Unix and developed a multi player version of SimCity for X11, did much of the core programming of The Sims, ... He is also known for having written a chapter "The X-Windows Disaster" on X Window System in the book The UNIX-HATERS Handbook.
I hope this experience helps you realize that jumping immediately to contempt can easily backfire.
