According to the United Nations in 2005, there were 600 million people with disabilities in the world. To use computers, many of them need special software known as &ldquo;access technology&rdquo;. Like other programs, these can be free software or proprietary. Those which are free software  respect the freedom of their users; the rest, proprietary programs, subject those users to the power of the program's owner. Programs for accessibility ethically must be free software, like other programs.
