Social media CEOs testify before Congress

Chief executives of social networking services have insisted at a US congressional hearing that they are working hard to fight the dissemination of misinformation on their platforms.

Facebook CEO Mark Zuckerberg, Google CEO Sundar Pichai and Twitter CEO Jack Dorsey testified before a House of Representatives committee on Thursday.

Zuckerberg objected to criticisms that Facebook's failure in handling misinformation about the presidential election in 2020 led to the storming of the US Capitol in January.

He said Facebook worked with authorities to identify and address threats before the attack, and that the company cooperated fully with investigations after the attack.
Pichai said last year Google blocked nearly 100 million ads that included misinformation about the coronavirus pandemic.

Regarding discussions to review a law that shields online platforms from liability over user content, Zuckerberg said his primary goal would be to help update the law to reflect modern reality.

Pichai expressed a cautious view regarding such revisions in documents submitted prior to the hearing.

US President Joe Biden has appointed as an aide a university professor who advocates breaking up IT companies. The appointment comes as those companies face increasing criticism over the spread of misinformation.
