It's very damaging to trade with the developing world if we start accusing companies of "attempting to colonize" because they have the temerity to expect people granted subsidised access to their website to actually play by the same rules as everyone else. I mean, if we start assuming that Angolans can't or shouldn't abide by the same rules as everyone else, it's very easy to just ensure services aren't affordable to the average Angolan again.
Angolans might have more reason to avoid paying for content than the rest of the world and they might have more reason to use Wikipedia or Facebook as a vector for delivering pirated content than the rest of the world, but the people pirating the content in this manner are at least as aware and deliberate in their circumvention of rules as crackers in other countries, and they should be respected for their clever hacks and blocked from uploading just like crackers elsewhere, and not patronised as people who couldn't possibly be expected to understand or accept Western mores.
