(Brazilian here with bad english) There isn't much interest yet. But that is expected.

Information flows somewhat like this here: First they ignore it hard, then media comes and make a fuss and that makes the gov. officials respond with disdain or support (depends on the strategy they adopt). But if it gets hotter something bigger magically happens to distract public opinion.

At least it is already on dados.gov.br, which is the brazilian portal for open data, meaning at least received some support from groups inside the government. But almost no interest from conventional media.
