I'm sure some Ruby programmers were attracted to Homebrew because it felt more familiar than something written in a language like Tcl. But Homebrew's fundamental tradeoff w/r/t purity was also a huge boost to installation speed at a time when most package managers for macOS still required you to build most things from source. That and the slick, user-friendly UI were probably the biggest factors for Homebrew's success when it came out.
