In it, SGI says, \u201cWe recently received a notice from [the] SCO Group stating its intention to terminate our fully paid license to certain UNIX-related code, under which we distribute our IRIX operating system, on the basis that we have breached the terms of such license.\u201dThe action against SGI is just another indication that SCO is broadening its complaint against the open source community. Earlier this year, SGI initiated a $3 billion lawsuit against IBM for alleged misappropriation of trade secrets and breach of contract.On Aug. 13, SCO sent a letter to SGI in which the company warns it will terminate SGI\u2019s license to Unix System V on Oct. 14, thus invalidating SGI\u2019s rights to distribute IRIX and XFS. In 1999, SGI contributed XFS, which supports large file sizes, to the open source community to increase Linux\u2019s scalability.An SGI spokesman says that SCO\u2019s allegations are without merit and that their license cannot be terminated.SGI users appear unconcerned.\u201cI think that the way SCO is going about it is ethically and morally wrong,\u201d says Avi Bercovich, director of a graphics design company in Amsterdam. \u201cIt wouldn\u2019t impact my purchasing or deploying of SGI hardware. If anything, I would buy double the SGI gear I need just to spite SCO.\u201d Bercovich\u2019s business uses a variety of SGI IRIX workstations for its graphics work.At the SCO Forum in August and in an Open Letter to the Open Source Community, SCO identified code it said SGI had contributed to Linux. In a letter posted on SGI\u2019s open source development site, Rich Altmaier, vice president of software at SGI says the company has since removed the code from its Linux Web site and released patches that replace the code SCO said was offending.
