Just as we do not install proprietary software, we have a policy of not making links to pages that promote proprietary programs. We cannot make proprietary software disappear by not talking about it; information about proprietary software is widely available, and people who want it will get it somehow. But we prefer not to be participants in the process of advertising proprietary software.
