"M-Pesa is not an attempt to recreate developed countries’ banking systems in Africa. Instead, it’s an idea which has been tailored to the Kenyan environment. Rather than giving up on poor, isolated communities as unbankable, it has extended financial services to their most apparently unlikely customers."
Where exactly are the alternatives demonized? The author simply suggests that tailoring a solution to an environment (in this case, Kenya) is ultimately more beneficial to those within the environment than a one-size-fits-all approach that only serves a privileged few.
Does not explain that it only works because the tellco is a public company (otherwise your money with them would be invested in risk) and the usabilities issues that allow a.lot of theft via social engineering.
