I guess I missed the part where you explained how it makes sense to apply a label like "not recommended because it supports non-free software" to OpenBSD but not to FSF (emacs, etc.).
As I've said, I think it's acceptable for free applications to run on non-free platforms (and say that they do), because this doesn't recommend the installation of those non-free platforms. But free systems should not recommend, suggest, or offer to install non-free apps. I follow these principles without discriminating between people or groups. Thus, I think it is legitimate for apps to run on Windows, so I apply this to both GNU applications and OpenBSD-related applications such as OpenSSH. I recognize that this can have the negative effect of reducing the pressure for people to move away from Windows, but I don't think that alone is a reason to reject apps that can run on Windows. Meanwhile, for operating systems, I endorse the ones that don't recommend, suggest, or offer to install non-free apps. I apply this principle to GNU/Linux distros and to BSD distros just the same. When people discover a recommendation for non-free software in a distro which is supposed not to have any, my first response is to show it to the distro developers and ask them to remove it. Everyone makes mistakes, so my aim is to get the mistakes corrected, not jump down their throats.
