Intellectual Property
The Sender ID proposal was the subject of controversy regarding intellectual property licensing issues: Microsoft holds patents on key parts of Sender ID and used to license those patents under terms that were not compatible with the GNU General Public License and which were considered problematic for free software implementations in general. On October 23, 2006, Microsoft placed those patents under the Open Specification Promise, which is compatible with free and open source licenses, but not with the most recent version of the GPL license, version 3.x.

Famous quotes containing the words intellectual and/or property:
“Our passional nature not only lawfully may, but must, decide an option between propositions, whenever it is a genuine option that cannot by its nature be decided on intellectual grounds; for to say, under such circumstances, “Do not decide, but leave the question open,” is itself a passional decision—just like deciding yes or no—and is attended with the same risk of losing the truth.”
—William James (1842–1910)
“By avarice and selfishness, and a groveling habit, from which none of us is free, of regarding the soil as property, or the means of acquiring property chiefly, the landscape is deformed, husbandry is degraded with us, and the farmer leads the meanest of lives. He knows Nature but as a robber.”
—Henry David Thoreau (1817–1862)
