I think Unotelly is still critical when it comes to cord cutting (or should that read disk ditching?) in SA. Netflix aside Unotelly offers access to so much more content both paid and free.So considering how little is in the SA Netflix, hardly anybody with an existing US setup would carry on paying for Netflix if they blocked VPN \ DNS trickery?
This is basically the situation:
Netflix SA < Showmax because DSTV owns too many rights
Netflix US / UK > Netflix SA / Showmax
