I guess a comparison would be: a megacorp invests in children in africa (schooling, money) so later they can hire them and make more money. Should we support this or resist?
You can have a whole one try to guess who is this.
And if you guess it right (I doubt you can answer wrong, lol) you would know a whole bunch of different reasons - including personal qualities of that "benevolent dictator" too.
NB honestly, if anything it's "his" OS what gave a lot of opportunities to the kids in the developing countries everywhere, not just Africa alone - just by providing the means to run the apps and games on almost anything. OLPC on the other hand provided an example how a specialized device made with the best intentions was a piece of shit.
