This is not correct. AZBox was the original and most popular theft of service STB in South America. They were transported to South America through the original North America AZBox distributor in South Florida.
There is no mistake about the AZBox ban in several South American countries. I believe this is the 4th country in the past year to specifically identify in legal documents, ban importation and destroy AZBoxes and the clones.
You are correct that they also identify the other brands that rode the coat tails of the original theft of service STB that has hacked South America subscription services for the past 5 years.
