GPL, Copyleft Use Declining Faster Than Ever

Brian Proffitt | IT World | December 16, 2011

A new analysis of licensing data shows that not only is use of the GPL and other copyleft licenses continuing to decline, but the rate of disuse is actually accelerating. That was the conclusion of Matthew Aslett's analysis of recent data from Black Duck Software, which shows that while use of the GPL, LGPL, and AGPL set of copyleft licenses dominates free and open source projects, that use is still on the decline.

"The GPL family now accounts for about 57% of all open source software, compared to 61% in June," Aslett wrote. More troubling for copyleft advocates, though, could be the projection Aslett and the 451 Group make based on the data. "...[I]f the current rate of decline continues, we project that the GPL family of licenses will account for only 50% of all open source software by September 2012."...
