[$] Apache disallows the Facebook BSD+patent license

Software patents may not have brought about the free-software apocalypsethat some have feared over the years, but they remain a minefield for thesoftware industry as a whole. A small-scale example of this can be seen inthe recent decision by the Apache Software Foundation (ASF) to move alicense with patent-related terms to its "Category-X"list of licenses that cannot be used by ASF projects. A number ofprojects will be scrambling to replace software dependencies on a shorttimeline, all because Facebook wanted to clarify its patent-licensingterms.
