James Anderson quoted in Linux and Open Source:
It’s hard to imagine having to use expensive, proprietary software for the computers we rebuild and send to high-poverty places in Africa. Linux being free and open is a boon for those kids who get the computers. Being virus-free means no necessity of costly virus-prevention software in a location where almost any cost is prohibitive. I visited one location where our computers were in use and found, to my dismay, that a popular operating system had been downloaded from street-purchased CDs. Several computers were so slow and unresponsive that they had been stowed as unusable. A friend and I took responsibility to stress the advantages of learning and continuing to use Ubuntu.
