What nonsense coming from the MXit camp (as expected), they had years in which to build a quality smartphone version of the platform but they actively chose to (as most South African companies do) cheap out on quality and sit on their hands and be complacent, thinking that they could just continue doing what they were doing and they would be okay.
I remember years ago when the iPhone came out, users were *begging* MXit to create a version of the platform that (a) wasn't clunky as hell and (b) was for their devices, and yet MXit took something like TWO YEARS to create an iPhone version and even then it was utter garbage.
It comes at zero shock that when better, faster, and more native applications (something that many users were begging them to address for years) started appearing for the phones, that they started losing users. As usual however, typical South African corporate arrogance, laziness and complacency ultimately killed them off. No-one caused their downfall but themselves.
