The biggest exception for freedom 0 i've seen is the license on the original JSON implementation http://www.json.org/license.html.

> The Software shall be used for Good, not Evil.

The JSON license is not considered a free software license due to this violation of freedom 0(not to mention all the problems with definition including the fact that many things could rightly be considered neither in Good or Evil and the license actually explicitly says it must be used for Good).

IIRC IBM got an exception from the author to use it for evil.

"IBM, its customers, partners, and minions."

Which reveals what a farce the 'no evil' clause is, since IBM has in the past sold typewriters to the Nazis, and probably has no qualms to do business with more modern evils either.
