Mark Zuckerberg and Sheryl Sandberg were to testify in the lawsuit involving Facebook in the Cambridge Analytica data privacy scandal.

That won't happen after the company reached a settlement agreement with the plaintiffs. As Reuters reveals, the parties involved have reached an agreement and requested a 60-day suspension to finalize it in a written agreement.
You can read the document that TheVerge reported, but so far there are no details on the terms of the deal.
Meta, as the company is now known, declined to comment and lawyers for the plaintiffs have yet to respond to responses from known SMEs. However, it's probably safe to say that Meta will be paying a lot of money to keep the case out.
So Mark Zuckerberg can only talk about upcoming virtual reality devices, instead of swearing in front of a court about what happened to his company during the 2016 election.
The lawsuit alleges that Facebook illegally shared user data with third parties and did not adequately protect it from misuse by malicious users. Zuckerberg had to answer questions from Congress in 2018 to explain exactly what happened to the Cambridge Analytica, a company that was hired by the Trump campaign team and was able to collect data from millions of Facebook profiles.
