What Telegram founder’s arrest means for the regulation of social media firms

Telegram founder Pavel Durov was arrested at a Paris airport and remains in detention, which the article presents as a sharp break from the norm for social media executives. French authorities extended his detention on Sunday, and on Monday the Paris prosecutor, Laure Beccuau, said the investigation concerned illicit transactions, child sexual abuse, fraud and refusal to communicate information to authorities. The article contrasts Telegram with end-to-end encrypted services such as WhatsApp and Signal, noting that Telegram encrypts only opt-in "secret chats" by default. Cryptography expert Matthew Green is quoted criticizing Telegram's marketing as a "secure messenger" despite this.
