Some time before 1989, ref="module.php?name=Lexikon&file=search&eid=1&query=Apple Computer, Inc.">Apple Computer, Inc. started a lawsuit against ref="module.php?name=Lexikon&file=search&eid=1&query=Hewlett-Packard">Hewlett-Packard and ref="module.php?name=Lexikon&file=search&eid=1&query=Microsoft">Microsoft, claiming they had breeched Apple' s ref="module.php?name=Lexikon&file=search&eid=1&query=copyright">copyright on the ref="module.php?name=Lexikon&file=search&eid=1&query=look and feel">look and feel of the ref="module.php?name=Lexikon&file=search&eid=1&query=Macintosh user interface">Macintosh user interface. In December 1989, ref="module.php?name=Lexikon&file=search&eid=1&query=Xerox">Xerox failed to sue ref="module.php?name=Lexikon&file=search&eid=1&query=Apple Computer">Apple Computer, claiming that the software for Apple' s ref="module.php?name=Lexikon&file=search&eid=1&query=Lisa">Lisa computer and ref="module.php?name=Lexikon&file=search&eid=1&query=Macintosh">Macintosh ref="module.php?name=Lexikon&file=search&eid=1&query=Finder">Finder, both copyrighted in 1987, were derived from two ref="module.php?name=Lexikon&file=search&eid=1&query=Xerox">Xerox programs: ref="module.php?name=Lexikon&file=search&eid=1&query=Smalltalk">Smalltalk, developed in the mid-1970s and ref="module.php?name=Lexikon&file=search&eid=1&query=Star">Star, copyrighted in 1981. Apple wanted to stop people from writing any program that worked even vaguely like a ref="module.php?name=Lexikon&file=search&eid=1&query=Macintosh">Macintosh. If such {look and feel} lawsuits succeed they could put an end to {free software} that could substitute for commercial software. In the weeks after the suit was filed, ref="module.php?name=Lexikon&file=search&eid=1&query=Usenet">Usenet reverberated with condemnation for Apple. ref="module.php?name=Lexikon&file=search&eid=1&query=GNU">GNU supporters {Richard Stallman}, John Gilmore, and Paul Rubin decided to take action against Apple. Apple' s reputation as a force for progress came from having made better computers but The {League for Programming Freedom} believed that Apple wanted to make all non-Apple computers worse. They therefore campaigned to discourage people from using Apple products or working for Apple or any other company threatening similar obstructionist tactics (e.g. ref="module.php?name=Lexikon&file=search&eid=1&query=Lotus">Lotus and ref="module.php?name=Lexikon&file=search&eid=1&query=Xerox">Xerox). Because of this boycott the ref="module.php?name=Lexikon&file=search&eid=1&query=Free Software Foundation">Free Software Foundation for a long time didn' t support ref="module.php?name=Lexikon&file=search&eid=1&query=Macintosh">Macintosh ref="module.php?name=Lexikon&file=search&eid=1&query=Unix">Unix in their software. In 1995, the LPF and the FSF decided to end the boycott. [Dates? Other events? Why did Xerox' s case against Apple fail?] (1995-04-18)
