The number of open source projects has grown considerably over the last ten years, actually exponentially according to a paper delivered by Amit Deshpande and Dirk Riehle in March of this year. According to Black Duck Software knowledgebase the most common open source license used by open source projects is the GPL version 2.0. According to that same source 94% of open ….
