Russian Foreign Ministry spokesperson Maria Zakharova posted a message on Telegram asking whether Western human rights NGOs would remain silent about Durov’s arrest after Western human rights NGOs criticized Russia’s decision to arrest Durov in 2018.

Telegram allows groups of up to 200,000 members, which critics say makes it easier for misinformation to spread and for users to share conspiracist, neo-Nazi, pedophile or terror-related content.

Cybersecurity experts said Telegram did remove some groups, but overall its systems for controlling extremist and illegal content were significantly weaker than those of other social media companies and messaging apps.
