Richard Stallman, a pioneer of the GNU operating system and founder of the Free Software Foundation, says that he is now motivated to try to ignite grassroots opposition. “It’s an issue of freedom versus power,” he said in a telephone interview from Taiwan. “Proprietary software is under the power of its developer, and it puts the user under the power of the developer. This is like handing out samples of an addictive drug–not something that schools ought to do.”
