I remember when this first started, back then it was apparent that this was a for profit coding school/low cost outsourcing play. They tried to get an in into some volunteer tech training work I was doing down in South Africa, but I turned them down because it seemed exploitative. The social justice angle pulled in all of the people who were too naive to look past the hype. Nice to see that people are finally waking up to this. There are lots more where that came from including in the US not for profit space that use lofty mission statements as a thin veil for the upper middle class and rich to line their pockets in the name of otherwise noble causes.
