Already underway. The Washington Post reports:
Facebook’s Sheryl Sandberg and Twitter’s Jack Dorsey tried to convince skeptical lawmakers Wednesday they are better prepared to combat foreign interference on their platforms than during the 2016 election.
Sandberg and Dorsey delivered their message at a congressional hearing about countries such as Russia that seek to spread divisive political messages online using inauthentic accounts — the second major hearing featuring top tech executives this year.
“We were too slow to spot this and too slow to act. That’s on us,” Sandberg, the chief operating officer of Facebook, told the Senate Intelligence Committee to open the hearing. “This interference was completely unacceptable. It violated the values of our company and of the country we love.”
