The former security director of the One Laptop Per Child non-profit has blasted the project for losing sight of its goals, accusing chairman Nicholas Negroponte of deceiving the public. It's all about shipping kit, says Ivan Krstić in an incendiary essay.

"I quit when Nicholas told me -- and not just me -- that learning was never part of the mission. The mission was, in his mind, always getting as many laptops as possible out there; to say anything about learning would be presumptuous, and so he doesn't want OLPC to have a software team, a hardware team, or a deployment team going forward," writes Krstić.
