FWIW, of the dozen or so blind programmers that I know, the majority use Windows, but a few use OS X, and one uses GNU/Linux on the desktop (Fedora, running GNOME and the Orca screen reader). So all three OS's are usable for a blind programmer. A bigger problem would be insisting that everyone use the same IDE, if that IDE isn't accessible (like, say, the JetBrains family AFAIK).
