Many Free Software developers wish to enhance their products by including features that are covered by patents. While it is often frustrating when popular features are protected by such laws, it is still desirable to respect potential users living in countries or regions in which such patents are recognized.
Even when a developer does not reside in a country or region that recognizes software patents (such as the United States), it is not a good idea to make patent-protected technology part of Free Software in such a manner that it is not easily identifiable and removed.
