WhatsApp has been banned for 72 hours in Brazil:

Brazil has once again opted to temporarily block the popular messaging service WhatsApp in the country. According to Brazilian publication Folha De S.Paulo, the block is scheduled to remain in place for 72 hours, affecting WhatsApp users across the country. The reason for the temporary ban hasn’t yet been revealed, but previous bans have come in response to Facebook’s refusal to comply with federal investigators in in ongoing criminal cases.

I suspect the reason they’re being banned isn’t truly “refusal to comply” but rather “inability to comply.” Not only that, but I wish that government officials would read the Wikipedia page on end-to-end encryption to understand why there’s no way to have any privacy at all with backdoors. Furthermore, the ban of WhatsApp is silly because even if WhatsApp placed a backdoor for Brazilian government officials, some other encrypted communication application will take it’s place.
