MS+Novell

In short, the pledge applies precariously to developers who work in a vacuum: those who write original software in their spare time, receive no payment for it, and do not distribute it to anyone under the GNU GPL. It's worse than useless, as this empty promise can create a false sense of security. Don't be confused by the illusion of a truce; developers are no safer from Microsoft patents now than they were before. Instead, Microsoft has used this patent pledge to indicate that, in their view, the only good Free Software developer is an isolated, uncompensated, unimportant Free Software developer.
