Maybe it's just me, but I find it very difficult to understand how your comment relates to the article.
maddog mentioned Chavez and the cuban embargo in order to illustrate a point, which is completely valid: Brazil and any other sovereign nation (excluding the USA... maybe) should be wary about using closed source software and computers made in a foreign country. You can never completely trust them; but there exist alternatives which you can implement right now.
Sorry if you had bad experiences in Venezuela, but you don't need to freak out and start a commie witch-hunt any time Chavez is mentioned. And I live Argentina, so I also have experience with enduring populist governments; but this article isn't about them, at all.
