I've been using Linux, traditional Unix editors like vim and emacs, and other keyboard-driven tools for the past decade with very little mouse use, and I'm starting to get RSI as a result. Singling out mouse-use for this is a wild claim, especially because typing on a keyboard involves far more RSI-inducing motions (many tiny repetitive finger-motions) than using a mouse.
Also, the author is specifically speaking about "Unx dogmatists" (not programmers in general), where using the mouse absolutely does* make you a rebel.
