Can you give an example of a net-freedom-reducing use<br>

backfired? Do you believe that _all_ use-based conditions<br>
are doomed to backfire, that we can't write effective ones?<br></blockquote><div><br></div><div>I mentioned the Berkeley SPICE one.

</span>That language reads:<br>
<br>
The license must not restrict anyone from making use of<br>
the program in a specific field of endeavor. For example,<br>
it may not restrict the program from being used in a<br>
business, or from being used for genetic research.<br></blockquote><div><br></div><div>While use restrictions are the main way that proposed licenses fail the field-of-endeavor language, they are not the only one. Coupling other license terms to fields of endeavor would also fail. No arguments about why the OSD should then ban the GPL, please.
