Answer
No, Roman Protasevich is no longer the editor-in-chief of the Telegram channel "Nexta". Protasevich was arrested by Belarusian authorities in May 2021 after his plane was diverted to Minsk. He is currently being held in pre-trial detention and faces charges of inciting social unrest. The Telegram channel "Nexta" continues to operate under the leadership of other editors.
