Google cannot find that quotation anywhere on the web.  Are you sure you 
have it right?  It looks like this might be the start of the thread you 
are thinking of:

http://kerneltrap.org/mailarchive/openbsd-misc/2007/12/10/486713

In that thread Stallman wrote "It looks like some people are having a 
discussion in which they construct views they would find outrageous, 
attribute them to me, and then try to blame me for them."  He does go on 
to say this...

    From what I have heard, OpenBSD does not contain non-free software
    (though I am not sure whether it contains any non-free firmware blobs).
    However, its ports system does suggest non-free programs, or at least
    so I was told when I looked for some BSD variant that I could
    recommend.  I therefore exercise my freedom of speech by not including
    OpenBSD in the list of systems that I recommend to the public.

...which is a different view than the one you attribute to him above. 
Can you document the source for your quote above?
