I thought his crime was not handing over data that he had specifically because the privacy on telegram is questionable at best? If just making a privacy focused app we're a crime we would see this more often. The trick is to make it so that you actually have nothing to hand over when authorities come knocking.
Everyone should be pissed off about this. But they just throw in the words "child pornography" and it's ok. I am totally against abusing children. I am also against government surveillance.
