The Netscape Public License, or NPL, as it was ultimately designed in 1998, is a free software license&mdash;but it has three major flaws. One flaw sends a bad philosophical message, another puts the free software community in a weak position, while the third creates a major practical problem within the free software community. Two of the flaws apply to the Mozilla Public License as well. Because of these flaws, we urge that you not use the NPL or the MPL for your free software.
