Earlier today 27 (update 16-09-2020: 30) civil society organisations sent a joint letter to Commissioner Breton summarising our responses to the Article 17 guidance consultation that closed last week... The letter expresses concerns that the proposed Article 17 guidance endorses the use of automated content blocking by online services even though it is clear that this will lead to the violation of fundamental rights. It also warns that implementations of Article 17 based on the proposed guidance will violate established principles of EU law.
