Adam Hadley, chief executive of Tech Against Terrorism, a group that combats extremism online, said: “We all know that Telegram is fundamental to the terrorist content ecosystem. However, we’ve tolerated it over the years because of low levels of awareness. What changed with this [attack] is we’re talking about hundreds of thousands of people knowing about particular channels ... all of a sudden it becomes a broadcast medium.”
