This has mothing to do with authoritarianism. Upholding the law itself is important. If everybody ignores the law all the time you'll have a pretty shitty society.

The Brazilian people have a clear option, vote for officials who have no problem with communication encryption. The solution is not to circumvent the parliamentary democratic process.

Nobody is going to question a law that nobody is willing to defy. And then you'll also end up with a shitty society.
