Microsoft has been sending Best Buy retail staff "training" material that deliberately attacks and in some cases distorts Linux, according to a leak from an anonymous Best Buy employee. The materials present obvious and at times true assertions about the lack of software support and users preferring a "comfortable" experience but also makes controversial statements about security and other features. Among these are contradictory claims that Linux doesn't get regular updates and yet is a problem to maintain precisely because it gets "hundreds of updates" per month.
