Right in the middle of the Amazon region there is a development zone where the majority of the electronics are made, in the country, by multinationals. It is called a Zona Franca.
When built in the country the import taxes, which represent the majority of the cost for imports such as electronics, these taxes are removed and make the good much cheaper.
It is the same with Xbox and PS4 in Brazil. An Xbox is 4 times cheaper than a PS4. If Brazil would be against USA or it's companies then it would be the reverse.
Hope I helped.
ps. Many people in country complain about the taxes but forget that when companies move their industries to Brazil, jobs, money and know-how stay there too improving the competitiveness. Sadly the vast majority of the population will look the price tag and complain without knowing the implications behind.
