If you are in Europe then you may have better enforced laws protecting you. If you are in Africa your government might not have the expertise and resources to spy on you. If you are in China, well...
For instance, something in the safe-harbor blabla says citizen data handled by public angencies in Europe is not allowed to go through US nor, obviously, to be stored in the US. This rule is not new: in my previous job we had to ditch gmail and gapps in order to comply, and it was f*ing painful.
So the GP is right. African governements in general do not have the means to spy on your electronic life.
