As a non Brazilian, sometimes when a government says a company is spying on its citizens, they mean that they want access, too, to the spying and censoring apparatus.
Maybe if I was in government I would think the same. Catch criminals before they act, stuff like that (I'm just being the devil's advocate here).
This is a dillema, and the worst kind. The kind citizens know nothing about, so the only possible way to talk about it is to speculate. I am, however, too old to speculate about these things anymore.
