On the other hand, using a government issued instant messenger seems even more dangerous. I think Brazilians have more to fear from their own government than foreign governments.
Well, fear of government and police seems to be some hip thing amongst some HN commenters. This doesn't make sense and shakes the whole foundation of democracy.
Do we really have democratic nations that would rather rely on some corporation than the government? Is brazil such a nation. That is semi-alarming to me.
