["Star Wars" film] 1. The AT&T corporate logo, which appears on computers sold by AT&T and bears an uncanny resemblance to the Death Star in the movie.
This usage is particularly common among partisans of BSD
Unix, who tend to regard the AT&T versions as inferior and AT&T as a bad guy.
Copies still circulate of a poster printed by Mt. Xinu showing a starscape with a space fighter labelled 4.2BSD
streaking away from a broken AT&T logo wreathed in flames.
2. AT&T's internal magazine, "Focus", uses "death star" to describe an incorrectly done AT&T logo in which the inner circle in the top left is dark instead of light - a frequent result of dark-on-light logo images.
