The FSF has published an essay by FSF President Richard Stallman in which he argues for the benefits of GPL version 3.
“The reason to migrate is because of the existing problems which GPLv3 will fix, such as 'tivoization,' DRM, and threats from software patents. Further advantages of GPLv3 include better internationalization, gentler termination, support for BitTorrent, and compatibility with the Apache license," Stallman said in a statement released by the foundation in May.
Tivoization, which refers to Tivo's software, is when computer appliances feature GPL-covered code that cannot be changed because the appliance will shut down.
Actual impacts of GPL version 3 could take a year or more to gauge, said Doug Levin, CEO of Black Duck Software, which offers a software compliance management platform.
"Right now, it appears there will only be a small number of projects that will adopt the license," but that could change, Levin said.
