None of that matters.This is faux outrage is about the best I've seen. In many areas one can pickup a charger from almost any place. Maybe if you live on Pitcairn Island you would have trouble getting a charger, but then you may have trouble with electricity. If you are new to electronic gadgets and one of the few that doesn't have a cable, charger and presumes no computer than yeah, you have to buy a charger.
Otherwise just use one from one the many in the junk draw.
No other country is going to follow suit because it's environmentally not a sound proposition.
The issue is that Apple is ignoring established Brazilian consumer law. Apple could have come up with method of satisfying their established law, a law they were aware of, while still achieving the environmental benefits of not putting chargers in the iPhone boxes.
