“Red Hat sold for $34 billion, but that money represents about 1 percent of Linux usage. Debian and its offspring have 50 times as many users as RHEL.”
Ian Murdock announced Debian on August 16, 1993. Ubuntu, Google’s internal gLinux and China’s Deepin all sit on top of it. Red Hat collects the money and the headlines from roughly 10 percent of the market, and 95 percent of that share is the free rebuilds it just killed. Debian does the work and Red Hat books the revenue.
