Re: I love how
The two options are:
1) The judge is a technical incompetent and unable to comprehend how properly implemented encryption works.
2) They are trying to bully WhatsApp in to creating a back-door but without going through the Brazilian parliament, etc, to do so in an open and properly debated manner (such as having a telecoms regulation that explicitly covers over-the-top providers like this).
The motive for (2) is probably not wanting to alienate the population or businesses that then see proper encryption as illegal and not something that protects you from the multitude of criminals (private or "state") who also want your information.
