Facebook, Google, Twitter and other tech rivals must try harder to be more effective, the European Commission said on Thursday.
The companies, including Mozilla and trade bodies for the advertising industry, signed up to the code in 2018 in a bid to stave off more heavy-handed regulation.
The tech giants had signed a self-regulatory code of practice to tackle disinformation two years ago, however, the Commission found lack of uniform definitions and incomplete application of the code by member states and platforms.
“As we also witness new threats and actors the time is ripe to go further and propose new measures. The platforms need to become more accountable and transparent. They need to open up and provide better access to data, among others,” the commission vice president for values and transparency, Vera Jourova said.
