For pedants: there have been some exceptions. The Netscape Public
License is FSF "free software" but not OSI "open source" as it gave
special privileges to Netscape. (I checked with Danese Cooper at OSI
on this question in 2002 and she confirmed this.) However, Netscape
used its NPL powers to relicense all NPL files as Mozilla Public
License, which is acceptable to both.

I don't know of any license that's OSI-approved that isn't also FSF
"free software".
