Last night's arrest of #Telegram's boss in Paris serves as yet another reminder that Telegram, despite the company's regular marketing offensives, is not a secure messaging service. Messages are not encrypted by default, and groups are not encrypted at all. Telegram has access to most of the content circulating on the platform, so the fact that there is no moderation is a choice.

Lots of people use Telegram because it's a good app and works well, but it's absolutely not a reliable activist tool.

I don't know what will come out of the current investigation, but arresting Pavel Durov is not an attack on encrypted messaging,
