Intel announced that it no longer will support the One Laptop Per Child (OLPC) project and resigned from the board over the group’s demand that the chipmaker stop selling its Classmate laptop in developing countries.

Intel in a statement said that the company remains a strong supporter of OLPC’s philanthropic goals, but were unable to agree to some of their requests, most notably that Intel cease support for non-OLPC platforms including the Classmate PC.

Intel’s resignation is considered a blow to the OLPC project, but the project is still supported by the U.N., the U.S. State Department and tech behemoths including Google, Quanta Computer, Microsoft, and Red Hat.
