In an open letter to Makate on Facebook, civic society non-profit Right2Know congratulated Makate. Right2Know used the letter to draw attention to the hypocrisy of multinational corporations which claim to support young black South African innovators such as Makate, but whose anti-competitive practices often strangle meaningful innovation. The letter also drew attention to the fact that South Africa's telecommunications duopoly (Vodacom–MTN) had led to the kind of unaffordable tariffs which made the "Please Call Me" service so successful with impoverished consumers in the first place.
