Programmer Richard Stallman's 25-year crusade to banish proprietary software from planet Earth hasn't had many victories. Most recently, One Laptop Per Child stabbed RMS in the face by replacing its Stallman-approved freeware with a Windows operating system. OLPC head Nicholas Negroponte, who originally backed a free-software configuration, believes it's a necessary compromise to sell the low-price laptops in a Windows-centric world. Stallman's response compares Negroponte to a drug dealer handing out free samples at the playground.
