Clones don't have anything to do with the bad original AZBox coding. As was indicated earlier, the problem affects all version 1 and 2 AZBoxes.
Clones don't impact bugs being made but they certainly reduce the chance of them getting fixed in future firmware updates. As you know, developers don't work for free so the more people buying clones, the less money coming in to keep paying the development team in order to resolve these issues.
