Could we be seeing a turning point for tech titans who reap huge profits for the "anything goes" content served up on their platforms? Free speech absolutists – including Elon Musk – are up in arms over the weekend arrest near Paris of the 39-year-old founder of Telegram. How strong is the case against the Russian-born Pavel Durov and his messaging app Telegram, which is popular among dissidents and pro-Putin milibloggers alike? Durov's detention comes as online hate speech and disinformation continues to spiral, as evidenced with the false narrative spun on social media during the UK's recent far-right riots.
