Is this what you're referring to? This deosn't indicate that they're disabling encryption, but that they're blocking all calls to Saudi numbers. A different issue.
There's an expectancy that we(I'm Brazilian) can understand and live with the consequences of Encryption, as any other democratic state.
But, in Brazil, Judges have a lot of power and they can make "undemocratic" decisions witch will be overruled by the superior instance.
Brazil do not follow (broadly) the stare decisis system in witch low instance judges must follow precedent upper decision.
In special repetitive cases, the Supreme Court can edit some enunciates called "súmulas vinculantes" that bind every branch of power (except legislative) to follow their statement but that's a exceptional measure.
As of today, there's only 55 "súmulas vinculantes".
